I need an ecommerce website created

I want an ecommerce website created preferably through Magento for around 1600 products. The products are currently being inputted into a Excel file which will later be converted into a .csv file so it can be uploaded easily.

The website will sell sports supplements/protein shakes and competitor websites include:
www.monstersupplements.com,
www.bodyshapersfitness.com,
www.elitesupplements.co.uk

I'm after a professionally built, modern website and the winner of this job must be open to revise certain aspects of the website if I am not happy with it.

If you are going to submit a quote please give a timescale of how long this project will take.

Also, if you need anymore information please don't hesitate to contact me.

Kind Regards,

Jatty
