Boy this fishing trip seems to be skunked.
If in Aggieland, starting at a window shop that sells/repairs custom screens might be the best genesis.
Here we go to Enercon, who builds 3ft wide screen frames with turning butterfly hardware to hold them in place to the 2x6 SPF frame others construct. They certainly work with framers toe to heel they can send you.
The other "possible" avenue is those Sunroom guys on TV that offer both Lexan and screens that interchange with the seasons. That said, novices can find leaks later where they didn't think out their roof to your roof connection & flashing .. if that's afoot in your case.
I won't bore you with internal netting similar to camping tents that are cheaper, EZier and maybe on Amazon.
Also don't think you want a stand alone mosquito gazebo kit that needs a framer to assemble.
Other solutions
Big fans, ceiling & floor = $$$$
OFF sprays
Some plants are deterrants
Pest sprays on auto cycles ... mmmm healthly?
Open flames ... ZAP!
Bug zappers
No birdbaths/other standing water + dunks if around
Other opinions
Screened porches trap the devils inside where reduced air flow can't help keep them away
Love to drink my ut-tea/TAMU-beer/ale watching them bounce against the screen trying to get me
