Hello,
Thanks for providing this opportunity.
I'm hoping online training (via Skype chat/email etc.) will work for you. If not, please accept my apologies and ignore my bid.
Otherwise, please note that although I'm new here at Freelancer.com (I signed up only a couple of days ago), I've had 12+ years of professional web programming/marketing experience including eCommerce and I'll be able to teach and guide you on everything you've asked for, and then some.
As a matter of fact, I have ghost-written well over 50,000 words of content for one of the leading eCommerce advice blogs - www.ecommerce-platforms.com.
Teaching and explaining web tech is one of my passions so I'll be able to put whole of my heart and soul into this.
I'll be happy to answer any questions you may have and hope you will favour me with this job, thereby giving a jump start to my career here at Freelancer.
With best regards,
Richa
