I'm not comfortable with posting specific names on a public mailing list (that's tantamount to self-advertising),
Your comfort level is up to you, and being reticent until you've established a strong record as a good Mailman citizen is the way I'd do it. :-) However, we've long been comfortable with minimalist self- advertising (ie, a one-liner of "I provide hosting services including Mailman at X Co." or "I recommend X Co, who I consult for") on list when somebody asks (especially in combination with a long helpful post ;-)
And we also have pages on the wiki explicitly for Mailman service providers and consultants. I don't think it's a good idea for third parties to list others there, but feel free to tell anyone you would recommend to potential clients to come to us to get listed (you need an account on the wiki to post there).
