Deluxe Cab Options

I am a new owner of used 2012 825i. Unfortunately it came with no glass or doors. I am finding it difficult to find aftermarket options for this curved roll bar. Should I surrender to higher priced OEM glass or doors or is there an option I am not finding yet? I found 1 hard door option but that is about it and I'd really like to start with a windshield and move on to the doors in the fall. Any sources will be appreciated.

Thanks in advance
