Hi,
This is Himanshu on behalf of QCoders. We have reviewed the details that you have posted here. We have extensive experience with Internet development and have developed a variety of web solutions, ranging from Client server applications, internet applications, web portals, real estate websites, B2b websites, community social networks, intranet applications, ecommerce websites, etc.
We have a very good team of very experienced designers and developers to get this task done easily.
We believe on "Quality Delivery on Time". There will be a 30 days bug fixing period with each of the delivery we do.
Also, we can provide you some of the ZEN CART websites samples we have developed if needed.
Looking forward to hearing from you.
Thanks
Himanshu
