It's a tricky one for a forum to answer, do you want someone discrete, or do you want it to look like you've paid a hooker to attend your social function? If you need someone discrete then factors about you like your age etc come into play, so the forum ain't really got the info to help you out. I also suspect that lots of working girls aren't so into this kind of social function thing so reverse booking might be a good option. Or try picking some profiles you like then searching the profile number on here, If do you own homework you'll likely find the best fit for you.
