Fashion Online Store - Website needed

Hello all,

I am starting a new online venture in drop shipping, whereby I will be selecting items from a wholesellers site and then adding these to my own. The site would require what you would normally expect from an online store, however please find some basic specification I will continue to ad to once i have selected the propsal that best suits my needs here:

1. The site needs to be both use friendly for the customer as it needs to be from the back end.
2. Adaptability is essential, so that i can ad new products, categories, subcategories, images, decriptions, prices etc with ease and speed.
3. The site will need to also need to be able to invoice a customer, send the invoice with items purchased to the customer with Vat and then record that order and the customers details against that order (details such as wholeseller item code, my item code, quantity, customers address, amount paid etc)
4. The homepage will need to be adadaptable and fresh allowing me to ad videos, promotional offers etc
5. The site will also need to be able to store customer details with their permision for monthly mail outs etc.

A site you could use to give you a basic idea would be www.sammydress.com however my site willneed to look cleaner, and higher end, there are of course a number of things we will not be offering making my site simpler and more efficient.

I look forward to recieving your proposals.

Justin
