Go for it. Do it. And - - -
try lots of other things too. If it works, do it again. If it doesn't, try something else. Buy a nice golf shirt and put your logo on it. You'll be surprised what comes out of the woodwork. See if you can do some accounting, bookkeeping, consulting or payroll for somebody.
Offer a Free 2nd look tax service. Put an ad in the local paper. You'll look over somebody's taxes and if you find something, offer to do a very cost effective amended return. You'll pick up another client for next tax season. And maybe a referral too.
Rent a table for $20 at a local community garden show, or weekly fresh fruit and crafts market. No one else will be discussing taxes or bookkeeping.
Network, take classes from NAEA or NATP. Get an EA.
Get involved with Community Service projects like Habitat for Humanity or HomeWorks of America. Volunteer with AARP / VITA / TCE. You can become a tax trainer, which heps you.
Last week, I helped an 85 yer old tax client move from one condo to another and took no money for the move. Well, I just picked up 2 new clients (her daughter and granddaughter) because of the help I gave to grandma. Neither had started their 2010 taxes.
It's simple networking, knowledge, and treating others like you would love to be treated. Like a trusted friend.
