Invite customer out side of Fiverr

[shamimdevs]

I got a client outside of fiverr who wants to work with me and pay me in cash through my USA relative. Since I have no one in the USA and I don't feel secure I told him to contact me on fiverr. So I want to invite him to Fiverr. I am not familiar with the process of inviting someone without sharing my Fiverr profile link. If anyone knows please can you guide me?
