I provide all what you need for this. Choose: - html or php pages - script to include in your code - ... - it can be customised for you (if the standard ones do not fit your need). You want to try it... PM me.
How much ? It depends of the effort and of the deal... Regularly, I charge NOTHING (0 !) but I ask for having at least a link to my site or a page of game. When I charge something, it is related to the development effort. Generally, it's a participation. In any case, the pages/scripts are automatically updated through my database of games. Feel free to PM me all your need (without commitment to buy something).
