Amazon Product Lister/Flat File and Shopify Experience

I need an Amazon product lister that is experienced with flatfiles and adding/editing product variations. You will create listings, fix listings, edit, etc. Creating and fixing listings using flatfiles can be very difficult unless you have experience doing both. Most of my listings are Parent/Child variations. Must be good with writing in US style English for product listings, descriptions, talking to me, etc.

You will also communicate with Amazon on service requests/concerns with product returns, lost/damaged products and whatever comes up.

Positive attributes that would be considered an advantage but not necessary.
- Shopify listing and management. (Will be opening store soon.)
- Amazon A+ specialist.
- Photo and video editing for Amazon listings per TOS .
- Arbitrage
- Wordpress/Shopify design editing

Please share with me your experience doing the above jobs. I believe in providing Bonuses or Rewards for completing projects in an exemplary fashion.

Here is the kicker - only 5-10 hours/week to begin with.

Thank you.
