I will give you access to my Fiverr.com account.
I will send you the funds upfront in Bitcoin (Btc) + Paypal fees + your fees.
You login and make the payment(s) via Paypal
to be honest, connecting Paypal, Bank card payment accounts with someone's Fiverr account is not a good idea at all. everything can be compromised very easily.
OP, I did a similar thing before but using only my Fiverr account. I received clear requirements from the client, he knew what he was looking for, so there were no problems in mediation. not even for revisions.
