Rock Valley will actually take your plans and build to order. They used to have a blank worksheet for you to provide dimensions and shape. They will do whatever you want, much nicer that just having to settle with mass produced parts.
They have an FB page too:

If you call, they will answer, and their' support is great. They've been around a long time.
