I need someone to build a flash sale ecommerce site as soon as possible

I need to someone to design and build a simple flash sale website like this http://www.wowcher.co.uk/deals/
the site has to include all the function, include sign in, payment, etc...

I want this website to be integrated into our current website http://www.baobella.com/
so there will be one section called shopping! and this eCommerce and be a plug in within the site.(our current site is build in silvertrip)

I m open to ideas! I need someone to build this for us as soon as possible!

the eCommerce site design would be the same style as our current ones!
