I think the lab equipment required depending on technique is 5-30 million or so for a infrared device prototype in a place that's like 'relatable' to industry (not a mad scientist in a barn using whatever means necessary, aka standard/easy)
I would not expect a low price for labor because its optics and that always gets hiked
Like do you have a basic idea for what it should be, or do you need ALL semiconductor/IC aspects designed? If you just need a technician to run your 'blueprints' and maybe adjust a few parameters for the machines thats one thing (i.e. you are like a pHd in optics that needs a chip made that you designed), if you want someone to give you a device with a data sheet that you just wanna use like a black box, that's gonna be another game.
And then do you need your device like mapped, tested, etc? (i.e. commercial shit related to defects etc)
like if you just want a barely tested bare die that you designed and are gonna bond and package yourself, you might get out 'alive', but if its the other thing, I think you will need some big money
