Wholesale product research for Amazon FBA

The initial task I am looking for is: 1. to find 4 branded products that are profitable on Amazon and available from a whole seller that the product can be easily purchased from in bulk 2. The cost to purchase these products plus the Amazon FBA fees must still yield a 30% profit. 3. The product must not be private label or have any IP issues and already have a few sellers, but not more than 6. 4. The product should be a best seller 5. Deliverable should be a list of the 4 products and links to them on Amazon; what they currently sell for; what the FBA cost is; the cost of purchasing the product per unit; a confirmation that researcher has already contacted the wholesaler and the wholesaler confirmed the product price and that they can ship to Los Angeles.
