For people who are talented in marketing and design, opening an agency may be a very real career option. It can give you the freedom and flexibility you may currently be lacking in your job, allowing you to work as it suits you.
Running an agency is no easy task though. There is an incredible amount of competition so you will need to be able to convince clients of your worth. You will have to market your own business properly before you are able to market a client’s business.
If you are going to go into business, decide if you are going to do it alone or with a partner. This could take some of the pressure of financially but it will also give you less creative freedom. Choose someone you trust and talk about specifics before you sign on the dotted line, like budgets, marketing tactics and the marketing and design services you will offer.
