What would be the best cheap screen? I also need some speakers and a portable projector room/box
I'm thinking the rock looking speakers for the back and some decent ones for the front since I can build a little roof to keep them out of the weather.
Kind of depends on what you call cheap...
The cheapest screen might be an old bed sheet. The definition of cheap begs the question as to what quality you want. Size will impact the price too. Will this be a permanent installation as it kind of sounds like it might be from your post?
With regards to cheap, many use recycled billboard vinyl. It's easy to get and a used 7' x 14' sized billboard tarp that will sell for less than $20. Just Google billboard tarp.
If you're not interested in the billboard tarp, you can step up to a new white vinyl tarp. Do a search for "movie tarp". The internet is full of dealers that sell them. Depending on size price will be maybe $30 - $150.
There are also cheap screens on ebay and Amazon. Keep in mind that you kind of get what you pay for on ebay and Amazon and quality will vary.
Perhaps the best screen value comes from Carl's Place. Carl's makes a beautiful, excellent quality screen for outdoor use at a very reasonable price. He'll make most any size you want. I would recommend the FlexiWhite material with finished edges.
Carl's also sells metal fittings that will allow you to build an excellent screen frame using 1" EMT conduit. You can also find similar fittings from companies selling vinyl tarps.
There are other options available depending on size, price, and how you're planning to use it.
Keep in mind that these type of screens are susceptible to damage from high winds and especially so if you plan to keep it up year round or through the season. It's best to put up and take down the screen material as needed to increase its useful life.
If you're looking at something to leave in place year round you might want to consider treated plywood or plywood with a plastic laminate surface. You can paint the surface each year or as need to maintain a pristine viewing surface.
