I am telling here something for you.

If you having item(ex:RP) first test it.

Then pack it properly.

then find a real company.

Buy paying company fees(all are not real).

Here some of telling with out fees I will get company(I don't how they gone get).

Your asking company proofs like (appraiser card, e3 license , fund proof).

Company will ask you what is the proof you having a RP.

Why they need show you proofs , with out proving your item.

So no company will show proofs before authentication of item(RP).

Company will come after fees paid.

So don't keep any doubts and spoil your deal.

ALL The Best
