Hello,
I'm really interested in your project. I already have lots of experiences in selling products (mostly fashion) on Amazon in Germany, UK and France.
It would be great if you could tell me more about the products. What kind of business is it?
The calculation of such a project is quite difficult. On Amazon it´s necessary to be active every day. You have to keep an eye on the vendor evaluation and the customer service. So I think it´s at least 30 minutes work per day. So I offer to you the help for those two campaigns for 350€ per week. Don't underestimate the work with Amazon. It´s important to always be active and try different things.
Best regards,
Frederike
