website development

Hi, I have a techo news based blogs which focus on latest mobiles ,tablets launch and apps review. I want to make specs and price comparison page ,i would provide the database in excel. The page should give the user option to select 2 or 3 devices from list and then compare their prices and specs. The specs would be compared from provided database and price need to be picked from websites like amazon. . I want someone who can add the functionality into my page and also provide me with interface wherein i can make more entries into database through excel only. Further this should automatically generate new ink of comparison each time i make a entry with other devices in database for search engines to find them individually also. Regards, Technopundit
