Hair extensions, how did you all set up and start off

[Allana_mami]

hi everyone I'm currently awaiting my hair extensions course next weekend, I'm going with belle hair, I was just wondering how everyone started up and what did you do when ordering hair or finding a supplier as I'm so eager I like things in place before I have any clients I would like to get the feel of knowing what I'm doing when it comes to ordering hair. I'm going to be training in. Fusion bonds, micro rings, easy shrinks & sew in-weave. And hopefully going back in a few weeks to learn more. I ain't got a budget but I don't want to go crazy money until I have a client base and have felt my feet in knowing what I'm doing .
All help on the whole subject would be so much appreciated and your story's/ experiences. X
