VA required for Amazon / eBay product sourcing

The main objective is to source products that can be sold on eBay and /or Amazon. Are you familiar with any software that helps achieve this task? For example, Jungle Scout, Helium 10, Terapeak, or other software?

It's not required but do you have any experience listing on eBay or Amazon?

Payment is for at least 30 hours the first week. There will be future work as well if product(s) are found within the first week that can be sold on eBay/Amazon.

Please provide examples of previous experiences.

Thank you
