Brad and Micah,
I don't think anyone considers either one of you two as part-timers, even though you yourselves probably do
By creating unique parts that are not available elsewhere you are offering priceless aftermarket to the CEG community. I think that the "part-timer" status is directed more towards the idea of reselling products on a random basis as deals fall into place. So keep doing what you're doing...as a matter of fact will you hurry up and make some more cool sh*t! :p
