E-Commerce site in WordPress Woocommerce

We want an E commerce site where we can sell products with the following:

– Specific layout which we want to show (inspired by an specified website which we want to give in private message )
– Payment options
-> IDeal integration (payment)
-> Credit Card
-> Klarna (payment module )
– Able to add photos (product categories)
– Add several options next to the product which can be bought (EAN number, and other options)
– Product inventory tracking as well BI modules such as best selling/FIFO/days in inventory; for this, we are ok to have template modules which work

We will pay AFTER the website has been delivered. We have bad experience in paying in advance.
Fixed fee of $ 500
