Personal loans platforms with only offer letter

I just graduated college and have a job with a 125k base in NYC but I have zero money at the moment to cover my moving expenses to the city and security deposits for an apartment. My job pays for relocation but I will only get that money after starting work. I was thinking of getting a loan to cover the moving costs and pay it back in under 3 months but most platforms require 2 paystubs or a W2, which I don’t have yet. Does anyone know a platform where I get find a loan for just an offer letter and employment verification?
