yeppers.
to go back to the OP and address the question directly. yes, there are people who will take your money and tell you how your poem could be better. far preferable, if you don't completely trust your work is "ready" for whatever secondary purpose you have in mind, is to buddy up to a poet who knows their shit and ask for some honest advice.
Far preferable indeed.
I believe Trish has a point about bleeding colors. Any writer, regardless genre, has to be leery of taking on another writer's style.
That said, I love the crit forum for the differing viewpoints given on a poem. The obvious things of misspelled words and such being brought to the poet's notice are small in comparison to different ways to think about how to approach an area in a poem that is causing the poet concern. It is always the poet's decision whether to take the advice or discard it--or use it as a spring board to dive into deeper waters. Having other poets crit my poems hasn't changed my voice, only honed it, because of learning when to take advice and when to discard it. Whether I agree with the advice or not, it is always invaluable to me because it requires me to think. And thinking is never a bad thing, in my experience.
I am also interested in the Church of Poetry. It would probably pay better than poetry does now, for one thing.
This thread is indeed a silk purse, Rob. Well caught.
