You can do it yourself. There is a ton of information on every Honda swap imaginable on the internet. Good thing about putting a b-series into your chasis is you can pretty much re-use everything. Also, if you put it in and have a problem, you can call a local shop, and if it's an easy fix they can tell you how to fix it over the phone, or if they can't diagnose over the phone you can just bring it in and have them fix it. It'll be cheaper that way.
