If you are a small solo op, I'm sorry, but you needn't spend big money on a CPA.
Just keep track of all your business expenses, sort in an Excel spreadsheet, and at the end of the season consult the IRS website to see what is deductible (most all business expenses are at least to some degree). Simple stuff for the solo guy.
Now if you are going big, then by all means..........
