Make money from your house by hosting a hotspot

Ok so a few days ago I was asked to setup a hotspot service at the 3rd Cup Cafe by flashing their router with dd-wrt firware and conneting it to a profile at www.hotspotsystems.com. It took me 2 days to figure out how to make the router work in a way were users are propted to accept an agreement before using the internet through their wifi. Then I found out Hotspotsystems.com can also charge people for using your wifi and deposit cash into your paypal account. So becuase I have a stelar internet connection I did the same thing to my old Netgear router and am now waiting for people to use my services. It is totally free for me even if they never connect and buy hotspot services from me. So I have one more old linksys router that I can install at someones house and will pay 50% of total profit if any of you are intrested. Let me know.
