It's not just the skills you're offering, it's when you're offering them: to make this work you probably need to be offering something which can be done without supervision, or from home, UNLESS the small businesses operate outside the 9-5 M-F day.

Different I know, but I knew of someone who asked for flexible working hours, to include one day from home and two days starting at 6.30 am. Which might have worked, had not answering the door and phone been one of their main responsibilities, ie they had to BE THERE when they were needed.

Unless your idea is to help small startups, who will be working all hours in the early stages? Where the trick is definitely knowing where to find them, and how to convince them that you're worth it: it's a fluid situation. Self promotion and advertising is almost certainly going to be necessary, but I'm not sure where you'd start.

Word of mouth may be your best bet: if you KNOW anyone running a small business - gardener, decorator - is it worth talking to them and asking if they are ever overwhelmed by ... sending out their invoices, chasing late payments, whatever it is you think you could offer ... and would some outside help be useful, enabling them to concentrate on the things they are good at.
