Not to be the devils advicate here, but when I started out, I jumped on one of those networking groups.
Just to find out that the people there were looking to get something done cheaply,, in return for you needing them for services.
In fact, one builder that I met in one of these groups ended up screwing me out of money. He joined the group because he ran out of contractors who would do work for him, and I was a "greenie".
Advise: Check references on those you meet and who need work done. If possible.
Dnk.......
