I used to have a few clients who were MTs but eventually they did not need anyone with my knowledge (and rates) to work on their taxes.
I would also suggest going to
www.irs.gov and order the following publications which will probably help a lot.
334 - Tax Guide for Small Business (For Individuals Who Use Schedule C or C-EZ)
463 - Travel, Entertainment, Gift, and Car Expenses
535 - Business Expenses
551 - Basis of Assets
552 - Recordkeeping for Individuals
560 - Retirement Plans for Small Business (SEP, SIMPLE and Qualified Plans)
583 - Starting a Business and Keeping Records
587 - Business Use of Your Home
946 - How to Depreciate Property
And also, if the time can be spared and at and minimal cost take a first semester Principles of Accounting course at a local Community College. Not necessarily to keep the books, but to get an understanding of what the business is doing.
Note that most small business fail within the first few years not because the owner did not know his subject but because they did not understand the accounting.
