Legit website where I can sell my Instagram accounts

Are there legit websites where I can sell Instagram accounts?

Why not the MP Social market place?

What is the procedure?
How much does cost escrow?
I have one 2k account and one 1.8k account so not much, can I post them there?
Also, how much to expect from these accounts?

You can contact me if you want to know more about our MPSocial marketplace. Thanks!

If you want to sell these 2 accounts, I’m buying, if the price is right.
