It would help to take a photograph of them or get them to have pictures of themselves to see how they photograph, I use to recruit girls from random places like school, malls, clubs, and if they didn't photograph well I would even bother recomend them anywhere that I know of webmasters who are looking for models like
www.69gs.com
so I would suggest since they are doing the amateur nautghy housewive thing to go on
www.southern-charms.com or
www.wildrosenetwork.com or
www.freakmommas.com or even
http://wjwebdesigns.com/recruit.shtml
if they can't take a few pictures of themselves its the red flag that they aren't that serious about being on the internet for anything.
even my girlfriend I tell them that get comfortable taking pictures of yourself and then take it from there otherwise it's just a giant waste of time.
a lot of girls out there want to get paid big for nothing. and if they can't even send a few pics of themselves why even bother.
