Hi, I have completely gone through with your
requirement and an idea running behind this project is much
clear to me.
There, I have enough Exp. in Magento Online shop setup and Magento extension development for large scale I can perform any modification whatever possible with magento.
I have successfully designed, developed, implemented and are maintaining several websites using Magento commerce. I am ready to
work on your project right now. So I request you to initiate
the PMB quickly so that we can discuss about different
approaches through which I can achieve your technical goals
within your time frame. Looking forward to hearing from you
soon. Regards, Technovation
