Sales Records Tracking Application

I need a windows application to track sales records and generate reports. I should be able to export records and reports to a .cvs file. I will upload orders in .xls format. Orders will be saved to existing customers matching by e-mail addresses. Tabs are : Last order date, Payment Method, Name, Email, Email 2, IP, Total $, ID, Address, Phone, Newsletter Group, Total Purchases Program will have search option by name, e-mail, IP, etc When I highlight the line, customer profile will be displayed on the lower screen. It will show customer name, ID, address etc and detailed orders. Main screen will pull info from the customer profile. Example; Customer Profile 6/8/2011 Paypal Joe Brown joe @ [login to view URL] [login to view URL] Acer Laptop 3 $800 5/3/2011 VISA Joe Brown joe @ [login to view URL] [login to view URL] HP Laptop 1 $600 Main Screen 6/8/2011 Paypal Joe Brown joe @ [login to view URL] [login to view URL] 4 $1400 There will be a few reports to generate, such as Customers didn't shop for 5 months (today<5 months) Report will be exported to .xls file Also need to have sort A to Z function (list by e-mail, list by Total $) etc There will be a few more future added, can not name right now but will decide while building the application. I need 7 days support. So if I need to add / change functions, they will be adjusted in this 7 days. There will be no bonus & extra payments in 7 days. After that if I need modifications, extra payment would be made. NO EXCEPTION; I need 100% codes. after receiving codes, I will create the same exe file and it has to work exactly the same way with .exe provided by you. Application will include sensitive customer information. I have to make sure that it is 100% clean. If you try to add any type of spyware & malicious code, you will be reported to the authorities.
