DD-WRT, Chillispot or WifiDog Hotspot assistance

We are a coffee shop. We are also a computer store. We wish to broadcast a Wireless Signal that allows us to charge for wireless in our community. We are only charging a dollar per day so using Paypal with Sputnik is not practical since paypal charges .33 per transaction and would receive 1/3rd of our income. We need to setup our own. We need someone with expertise in accomplishing this. We will supply a wireless router that has either Chillispot or WifiDog installed on it as part of the dd-wrt mega firmware install. We need you to teach us how to use this router to create a mysql authentification system for accepting credit cards using our existing credit card processor ([login to view URL]) that passes PCI security requirements. Please do not respond to this if you do not have expertise in this area as we cannot carry you on this solution. We will be relying on your expertise and along with our previous research. The final goal for us is to be able to 1) Allow someone to see and log onto our wireless signal but intercept them for authentification. 2) Allow them to pay, or be a guest on our system. The payment solution we will be using is PayJunction. We can provide API information for that. 3) The solution must pass the PCI Compliance requirments. Thank you. Jay CompuMatter
