The place that I've seen people usually ask this question is in the "Advertising for Players" forum. Not sure if that is the right place but it seems to fit fairly well.
Of course, regardless of what you ask there will be a huge number of replies along the line of "Well, we basically fit your requirements (read we are nothing like what you want) so why don't you come try us out. We're a really friendly mud with great administrators. Stop on by and ask for XYZ"
