Hey there,
To not writing a long and boring proposal, let me just talk about myself and why I can help you on this project :)
I have great knowledge about our popular shopping sites like Hepsiburada, GittiGidiyor, Trendyol, N11, etc, and even on the not popular ones.
I'm also familiar with all of the customer/selling policies on both;
*sites that are selling for themselves (like Hepsiburada, Amazon)
*sites that are just a place for third party sellers (Like GittiGidiyor, eBay)
What I mean is, as a hardcore online shopper and a hobby online seller, I believe we can discuss the kind of help you need, before awarding the project. I'm quite confident about helping you, no matter whats the topic is.
Looking forward to hear back from you, have a great day :)
