How Can I Publish My Poems

i have a collection of MY OWN POEMS, Its quiet a collection. i keep them because i love reading my own work esp. when i am "down". of recent most of my friends have saw it and told me they r good,  i didnt take it serious untill one of them posted some to the poetry colunm of online nigeria, the comments it recieved were encouraging and now poeple has been asking me to publish them but the issue now is that i don't know how to go about the publishing, can any one be of assistance?
