preferred passport, government issued photo ID card is also OK. The drivers license is not an applicable form of KYC document.
OP just answered and apperantly you will have to send documents to him, instead of the company asking for KYC. You might want to be extra careful because there has been cases of doxxing in the past.
The good news is that OP is willing to escrow the amount, although it's kind of hard to verify whether they accepted the documents for KYC because he said he would release partial amount after getting the documents, and partial amount after getting the documents approved by the company that wants KYC.
Edit: Apperantly OP is willing to give you a login to the site but im not sure if getting the documents out from there is possible.
If OP is ready to give login details of this site then I am also ready with escrow but I am not going to give my details to OP because its very risky I will upload in account and as its approved then I have my money and I don't like to give any details to OP if agree then send me message we can do this right now
