they will not & should not discuss the details on a public forum like this...  invites LE & creaps to try to beat the system, to the ladies detriment.  
Some ladies have rigid policies while others are more flexible, offering alturnative screening for newbies, self-employed, retired...  All you can do is tell her the truth, see if you can provide enough to make her comfortable seeing you.  If not, no harm, no foul.  Move on, maybe circle back later if you get referances.
Sometimes a screening service is a help.  Look through other posts for the names of reputable services.

I am relatively new and had the same difficulties as you finding that first provider. I found a well-reviewed veteran provider on TER and emailed her.  We exchanged some emails, and i called her on her TER listed number.  We talked on the phone and she took a chance on me. After i met her, she gave me a reference, I became Preferred411 and Date Check approved and now I am golden.
