Dear Sir,
I have 3 year experience in Asp,Asp.net i can design e-shop for you according to your needs
System will include Admin Control panel so that you can add/delete/edit Departments->Categories->Products
Also there is an Order Managment System,Senstive Data of your Customer should be stored in encrypted form so that no one can read it, Data will be decrypted dynamiclay
Passwords of users should be stored in HASHED form
so that no body can access it in case of any sort of attack it means we have full secure web application
You can expend this product as much as you need
i-e
Now if you have 2 departments if after few months you need to add 1 more department and its categories as well as products the you just go to control panel and click on add Department the add category and tghen add products,website will be automaticaly updated
we wil take less then 40 days however 40 is upper bound,more info about system will be provided on contact
Thanks
