Introductions

I have no musical knowledge but I have been able to compose a number of melodies by picking out notes on my portable electronic keyboard.These tunes  will be part of a musical, the script for which, I have already written What I can't do is to put chords to my melodies. I have read many articles about this subject all of which tell me I have to experiment. This is difficult when you can't play an instrument. Therefore I would like to contact someone who would be willing to help me orchestrate? my music.
