Yes we are here. You have two problems..
1. If you have done air purging(bleeding) of a system before then a question or two wouldn't hurt. If you have never done it there are too many tricks of the trade that you might have to do while purging the system. Safety first! In which case you should get a pro to tie in your pipes.
2. If you have done purging before please post two or three pictures of your existing heating system and ask a specific question and I would be glad to help.
