I have always said, if there is one thing I could do over again it would be to have worked for someone else prior to starting my own business. This would give you the opportunity to learn the business and pick up on tips that you would not learn on your own! Just something to consider! However, one spring clean up job could be completely different than another, therefore it is hard to give you a "cookie cutter" answer.
I wish you the best and good luck!
