Amazon Product Sourcing

I'm looking for someone with experience with product sourcing for my amazon dropshipping business. My criteria is as follows: at least 25% roi after fees, products that sell for a minimum of $50 on amazon, sales rank no higher than 200,000 unless monthly sales are good via amz scout or jungle scout. Tools that I have used in the past have been priceblink, cleer platinum, rev seller, amz superman tool amazon without fees, prime away....I think thats it.

I'm very open to other tools that are proven to work. Applicants must show me proof that they have amazon product sourcing experience somehow. Provide a spreadsheet or past clients sales for their amazon stores.

P.S. If you have never sourced products for past employers for Amazon Dropshipping please do not contact me. Sorry but I ask for proof and if you cannot provide proof then you're just wasting your time by contacting me. To everyone else who has had experience that can provide proof well then I look forward to hear from you. Thanks:)
