How much does it cost to hire a lawyer to just check your marriage based green card application forms?

Most lawyers will not provide that limited service, to avoid any liability for what happens to the application later when they are not the "attorney of record."

You need to reach out to specific attorneys and speak to them. Each attorney is different as is each case. Your question is not as simple as you might think. It wouldn't take long for an attorney to look over the application and tell you whether or not you have filled out all of the necessary sections, it would take much longer for them to tell you if it was done correctly. That would require knowing your background information.
