Keep an eye on how the site ranks. If it slips, put another keyword optimised article on the page.
Charge anything from $50.00 a month up to $500.00 for the space. Higher ticket items like Real Estate agents will always pay more as just one sale gets multiple times a return on their monthly investment with you.
If they question your price, ask them how much, say, five or ten leads per month is worth to their business … surely they'll see the value in your offer.
This blueprint is handy because you don't need to approach local businesses trying to get to build them a website when they've already got one, you're simply building a different one which belongs to you … they are just renting the space on it.
Let them try it for three months then, if they like it (and they should do), they sign a 12 month contract. Or, if they want to pull out they must give 3 months notice to give you time to notify the guy who's waiting, that the space will soon be his.
Over a short time, all ten websites should be earning you an income.
So you could be earning an average of $1000.00 per month quite easily.
