Yellow Pages

Hi, I need a script similar to The Yellow Pages, Basically i have Excel sheets with property owners details (approx 10 search feilds on each) all must be searchable, the results of the search will be strict, only 3 results per search will be allowed, the user will have to pay for this service Via monthly/yearly subscription or deposit money in return for "search Credits" this needs to be easy to update as i will be regularly updating. i will need the usual member registration auto email reply etc, no need for web design as i can do this myself, its only the database in not familiar with. i'm ready to get this started ASAP
