For providers that require a work number for screening, what do you generally take if a client is self-employed? Normally on a page with the screening requirements it's usually written in BIG BOLD LETTERS that if any information is missing, you will be ignored. Any providers on here have any alternate methods they prefer to use to screen clients with no work number other than their own phone?

Not an escort, but, I am certain most of them have dealt with extenuating circumstances before.  Best bet is to email them ahead of time and ask what they would prefer to complete screening to their comfort.  That way you can provide it in their form or in an email, etc.  You may be out of luck with some providers but others will have ways to screen you.

I would probably also communicate a specific intent "looking to schedule with you next week", etc so they have an idea of the time frame in question.  

Finally, look into screening services like p411, date check, and room service.

But we tend to not be too keen on posting our screening methods on a public forum. Each lady is different, but if you mention it in your first contact with a given lady, I'm sure she'll have an alternate screening method that she can walk you through.

Since you are self employed there are other ways to screen. If you would like to know more feel free to send me a pm.
