There are many other companies out there that can print/make custom PCB for you.
If you are looking to making an encloser for a project, I would suggest looking into 3d printed options. I know groups that have products like carloop's whos enclosers are 3d printing.
This does require doing some modeling on your own. Although, if it is not your cup of tea, it is normally not to hard to find someone to do the modeling for you.
3d printing options vary in cost based on who you use, the material used, the size and quantity of the order, etc. I find I normally get the best price on 3d printed stuff working with a local group. They are often more willing to bargain than companies operating online.
Hope this helps.
