Do you think this is a good business idea?

As you may know, small businesses like individual retail stores etc can’t afford to pay or hire a full time marketer.

SO.. i was thinking of starting a small business in my spare time to market small businesses websites for a small one-off fee e.g $500. This would include everything especially recommendations.

I have a degree in marketing and many years experience in the industry.

That is an excellent idea. Even small businesses are realizing they need a web page for their customers. Keep it simple and remember at times you will be dealing with the computer illiterate. Good luck.
