Why is it this hard to find a vocalist. Thousands of people are posting things on this website and it is rediculously hard to find a vocalist for our band. Why ? 
Visit karaoke bars and listen to singers, anyone with talent introduce yourself to
Contact any vocal instructors (check big music stores for these) and ask if they have any star pupils
Put an ad in your local classified newspaper (American Classifieds for example) stating you need a singer for your band. Put the ad in the miscellanous section where people are selling just about anything. Thousands of people read those sections. Odds are a few of them can sing. (I've found singers in the past with this method)
Go see some of the local bands in your area, if you hear a good singer introduce yourself. You'd be surprised how many unhappy musicians there are, one may join your band.
There are other websites where you can advertise (Backpage.com, Craig's List, Community Musician, etc.) Bandmix is a fine websie but there's other good ones too.
Tell every person yu know you're looking for a singer. Somebody is bound to know a singer. Years ago I found the best drummer I ever played with this way.
Good luck...fisherman bob
