Good place to get a flight case made?

[johnbegone]

I've looked into getting flight cases custom made and it's ridiculously expensive but I just bought the Sunn 300T from Ty on this forum and I need to protect it. I haven't had any luck finding some other kind of case that it will fit in, so if I were to go the custom route, what's a good, affordable company to go through? I'm located in Illinois if that makes any differences.

Thanks for the input!
