Does he have a truck? Maybe put the company name and phone number on it if it's not already?
I know that I see a ton of vehicles around here like that.
Business cards can be a good idea. I have gardenhelper cards and I pin them to the walmart board when I go in. It works, people take them.

Not sure how to go about buying a website though. I got a free one with my verizon and I can sell stuff on there if I want.
