Projector and screen needed.... please help

I need a projector and portable screen for work presentations…

Doesnt need to be a super awesome resolution, its going to just display very basic powerpoints and needs to be portable to fit in the back of a 3 series coupe…

What should i expect to pay and what should I be looking for?

Thanks

Mind you these are for a conference room/ dining room presentation… my screen is only going to be 6 ft wide at most… so other than size limits of 100 inches, will these be bright enough? etc…

does quality matter?

does price matter?

Yes, brightness matters, but Id imagine that when it counts, the room will be able to be dimmed.
Screen size will never exceed 100 inches… most likely 5-7 ft will be adequate.
Quality isnt a big deal, its just power point… id doesnt need to be 1080 or anything.
Price… cheaper the better. This will most likely one be used less than 15x a year.

I have all of the above, and available for sale. I have a ~40-50" diagonal foldable screen, and an IN24 InFocus 1800 or 2200 lumen DLP projector with low hours (<10) I always used someone elses while teaching to save my bulb… lol.

Actually had a picture on my phone from when I pulled it out ages ago surprisingly enough.
