Hello,
I'm very interested to complete this task for your full satisfaction. I'm on internet marketing just like you, and been making sites in shopify and amazon reselling and dropshipping. Getting pictures on estores are just easy and really obtainable in alibaba, ebay, etsy, etc. as long as the product fits with the attributes then it can be downloaded.
I have here a PC at home with fast internet connections and I am very available right now to download pictures with your specs.
Hope to hear from you soon,
Ruel
