Marketing agency
A marketing agency helps businesses attract customers through services such as strategy, paid advertising, content, SEO and analytics. You can begin from home with a focused service, but finding clients and delivering measurable work take time.

Who it suits
This may suit someone who enjoys understanding businesses, communicating with clients and working on marketing. It helps to have experience in at least one service you can offer, such as social media, paid advertising, SEO, content or analytics.
Businesses may pay for help reaching customers, improving their marketing or understanding what is working. A focused service with clear tasks and reporting makes it easier for a client to see what they are buying.
Step by step
- Choose one client type and one problem to solve. Pick a kind of business you understand and a specific marketing problem it may have. For example, you might help local shops improve social media posts or help a service business understand website traffic. A narrow offer is easier to explain than doing every kind of marketing. About 1-2 hours.
- Choose a service you can deliver well. Select one service, such as paid social, SEO, content or analytics. Write down exactly what the client receives, what you need from them and what is not included. Be honest about your experience and do not take on work you cannot deliver reliably. About 1-2 hours.
- Make a clearly labelled example of your work. Create a sample audit, mock campaign or example report that shows your approach. If it is not real client work, label it clearly as a sample and do not imply it produced results. Keep the example focused on the service you plan to sell. About Half a day to 2 days.
- Write a short client brief template. Ask about the business goal, audience, current marketing, obstacles and what success would look like. Include space for the client's budget, approval process and the information you need to begin. Use the same questions for each new enquiry, then adapt them as needed. About 1-2 hours.
- Find and research prospective clients. Look for prospects through referrals, local business networks, industry directories, agency content and online search. Make a short list and note what each business does and why your service might help. Avoid sending the same generic message to everyone. About 1-2 hours per shortlist.
- Talk with a prospect about their needs. Ask about the client's sales process, goals, current marketing and constraints before suggesting work. You can have the conversation by email, video or phone, depending on what works for both of you. Be clear if you are not the right person for the job. About 30-60 minutes per conversation.
- Send a proposal with clear boundaries. Set out the work, each person's responsibilities, how progress will be measured, approval points, payment arrangements and how either side can end the engagement. Make the scope easy to understand and explain how extra requests will be handled. Ask the client to confirm the terms in writing before work begins. About 1-3 hours per proposal.
- Agree how you will report progress. Decide what evidence you will use, how often you will report and who will provide access to campaign information. Explain that results can depend on the client's offer, sales process and budget, not only your work. Avoid promising results you cannot control. About 30-60 minutes to agree.
- Review the project after delivery. Compare the work with the original brief and note what went well, what was unclear and what you would change next time. Ask the client for feedback and whether they would be comfortable providing a testimonial. Only use a testimonial with the client's permission. About 30-60 minutes.
Your first 15 minutes
Choose one service and one type of client, then draft a one-page offer and ask three suitable business owners for feedback.
The money
Price a defined piece of work or a clear monthly service, and include your time for planning, delivery, communication and reporting. Consider your business costs and tax responsibilities when setting a fee; agree what is included, payment timing and extra-work charges in writing. Client fees are not the same as your take-home pay.
Example only: For one UK month, one client pays £500 and your costs are £60, leaving £440 before tax (£500 - £60). For one Ireland month, one client pays €600 and your costs are €70, leaving €530 before tax (€600 - €70). These are made-up figures, not typical prices or an earnings promise.
