Need a male vocal on my 70s-style rock song

I'm finishing a few original rock tunes that I need a Male vocal and harmonies for. I wasn't satisfied with the last lead vocal, and need someone who can redo everything with the harmonies. I'd like to get it done in a month or two, and I'd like to ask the five "favorites" of mine to give me a price. I have the original live tape and the vocal I wasn't happy with, for comparisons and discussion

Additional info:
The song has less than 10 tracks recorded that need mixing.
