Cost for a lawyer to revise contracts

[Fernando Vargas]

I have a contract that I’m using for seller financing that id like reviewed by a lawyer so i could add any laws or codes that are left out. I found a lawyer online on upcounsel.com that charges me a flat fee of 800$. Im wondering if this is average for a contract review or if its a bit higher than average. I don’t mind paying it, but I’m just wondering if i could find a better deal first. Its 3 pages long and im located in Bakersfield Ca. Thank you!
