Matching windows - doors - hatches??


Hi guys,

I seem to be having a hard time finding this information. I am in the process of planning a DIY composite habitat box build. I am looking for a company to work with that makes matching doors, windows and hatches. I have seen several companies out there, but all seem to make 2 of the 3. Any help with this would be appreciated. I need to source these in the USA. Thank you!
