you may be able to get provider status by 'vouch' and not review. talk the mods in your area. i know that from another place and time that was how you got it. i am sure they would have to be registered members.
also, the best advice ever...network, network, network. by reading and pay attention you can tell who is reputable and screens and can be trusted. those are the ladies you want to contact and ask for help when screening, they are the most likely to answer and help as they are usually the most concerned with the safety of others as well as themselves.
