Starting a Wisp - Business Plan things

If you are not tech savvy and are looking to put together a solid business plan for a WISP you should consider the following:

-What are you going to charge? This seems obvious but can get complex.  Are you going to charge an install fee? What are you going to pay installers? Does the customer or you own the equipment?

-What service plans are you going to offer?  Have you compared your plans to competitors?

-Will you be offering additional services? VOIP? e-mail? Web-hosting?

-Do you have a service level agreement with your customers? What do they expect when the signup? Do your customers sign a contract?

-How will you do technical support? How will you do billing? What are your billing policies?
