Small gallery in NYC wants to represent me - there is a fee in the contract. Is this a scam?

I was recently invited to submit my portfolio for potential representation at a small gallery in NYC. They just called me letting me know they want to represent me for 1 year, and sent over a contract. Im looking at the contract and it says in one clause:

"Promotional representation feee of $2400, for One Year of representation, paid upon signing. This fee is non-refundable"

Is this a scam? Or is this standard practice at galleries?

I have zero professional art experience, let alone gallery representation, so i am not sure about how this works.

Thank you

EDIT: Gallery name: Amsterdam Whitney in NYC
