Electronics A P P

this website will be selling extended warranty to customers the customer will be registering their product one my website (for ex. cell phone) it will have different fields make model serial number etc and then a secure payment method via creditcard or paypal basically i will be selling extended warranties to those people who buy items from smaller stores they can register on this site and pay me, and when it comes down to if something happens i will repair/replace their product (currently I will only be doing cellphones). It will need a database of cell phones which I need an easy way to access and add more phone make models. also the date of purchase cannot be more than 7 days from the date of registration. A customer cannot register for extended warranty 3 months after the date of purchase when something has gone wrong and they wish to save money on repairs. charge will be 10% of the cost of the item retail value -a confirmation of registration email will be sent to the company email address and as well as the customer -an invoice will be sent to the customer email address Further details can be provided if interested. Thanks
