That pricing sounds way
out of line - "special order" or not. Check out ebay (as others have mentioned) or OutdoorFabrics.com
Most of the patterns are under $25 per yard and the entire line seems to be available.
But, any upholstery fabric will do for a gaucho - yardage will depend on the design of your particular gaucho, the width & pattern (matching patterns or stripes?) of the fabric selected - but should be in the 6-11 yard range. Use your old upholstery and make a pattern out of paper to figure it out.
Also, if you want to save a little money, use a less expensive fabric on the back/bottoms (wrong side). But then you cushions aren't reversible.
