In the year of working on Fiverr, I have had numerous messages from other sellers.
“I am new on Fiverr please help me with my gigs.” Or “I am a teacher, won’t you employ me!”
There is one big rule here: Do NOT message other sellers! It is not done on Fiverr.
Also, do NOT sell your services on Buyer Request, this is only for sellers.
I hope this is helpful!
