Once in a great while 11X14 color film becomes available, but the largest
standard size is 8x10. Getting anything custom cut bigger would involve a
minimum order of many thousands of dollars, if anyone would do it at all.
Your budget isn't very realistic for getting even into 8x10 color. But you
could find a reasonable bargain on some kind of used 8x10 and lens, and
perhaps find some outdated 8x10 chrome film at a discount, just to practice and study on a lightbox before you try something more ambitious.
