Answer 1

With all due respect, hobby stores and home improvement centers will have some of the highest markups you will find, so the valves might be a little pricey.  If not, I offer my apologies.

Several manufacturers make miniature pneumatic valves that will actuate on 12vdc.  You can Google people like, Parker, Watts, Red-Hat, SMC and Mack to name just a few.  You can also go to mcmaster.com and buy one on-line for about $25 and get it in a couple days.  Look for thermoplastic valves rather than brass ones, you will save a lot of cash that way.

And by the way, if this is really for costume use, you really do not want to use 250vac.  That will fry your butt for sure.  Stick with the 12vdc.

Answer 2

Automatic lawn watering valves are probably the least expensive type of solenoid valve available. If you need something that is better fo air, look for robot hobby supplies.
