If you do an internet search for publishers you will find an abundance of them. You will have to pay of course but just look for the cheapest and best offer. As for copyright. While a person is still living their work is automatically copyrighted by them and proof is merely the name and date with the poem, However this may change once a person is deceased and you may need to look into that side of it. Some Publishers will give you that information anyway. But you can do a search on the net for copyright laws for the uk for example that will probably tell you all you need to know. In reality copyright is hard to prove for poetry so I am told.
