Websites-Database/Ecommerce (Dynamic)

1. first product
I have a data base consisting in few tables (up to 10) and I need to present information from them to viewers. I need search, add, browse through fields…
I do not know how to describe in words the application.

Ideea:
I want to offer to people voicemail on a phone number allocated by me.
They call to a number, get a free number, configure it as they want to work and then advertise it.
People who call will be able to hear the recording, replay, leave a voicemail or get the call redirected if the ownver activated this feature and bought a prepaid card for this service.

I need a web site to present the service, allocate numbers, show them how it works and encourange them to use my numbers and service.

Pls let me know if you would be interested and I will make another description of the tables and iformation I need to be manipulated with all request.

Main product:
it is an inventory of people and products online.
it consist of area, categories and goods. There is a database which shows the location, category and availability of the good in that moment.
The goods should be registered, update description files, choose area and category of the service.
I will give complete details if we agree on the base conditions and when we sign a NDA for this.
