I want to start Amazon FBA wholesale USA business

I have a budget of 2000$ and I also have LLC in Florida.

I also have knowledge about Amazon wholesale but I am very confused what should be the best strategy means first we should hunt products then apply for approval or first we hunt brands apply for approval then hunt products.

I need advise from some expert sellers what is best strategy… kindly guide me from step 1 to last step ( shipment to Amazon )

With $2000 use the brands first strategy find 30 small brands call to get 5-10 approvals, then analyze their price sheets to buy 3 brands x 10 units each to test and reorder only the winners
