Hi,
Kindly check my freelancer profile and reviews, I do have 11+ years experience on amazon and can manage all your work needs.
I have worked for various amazon categories, so can share the sample work any of the categories you are looking for.
I do always prefer to upload the products using amazon flat files of each category, as it works faster than the manual upload. Only for sell similar products I do add them manually as it requires to fill only few fields.
Here is my expertise area of work for Amazon and all other US and EU top marketplaces I worked for.
1. Inventory upload and listing optimization.
2. Image enhancements.
3. Keywords ranking and improvement.
4. FBA management.
5. Customer support and Order processing.
6. Returns and refunds management.
7. Feedback and account performance improvement.
Thanks
