Sounds like you plan on offering to do individual consulting with homeowners. Great idea; however, don't stop there. Obviously, these clients would be local to you. Publish an ezine and you'll see your list build with clients all over the place. Your ezine (or blog for that matter) would offer basic tips, etc. You could also create a 7 part ecourse and have your subscribers sign up for that. This would all lead to an information product that you create with all the info and tips that you can offer your clients. This way, your audience is wider than just the local people in your area.

Hope that helps...look forward to hearing more.
