Hey man, I just did my headliner with black alcantara and actually used riggsbros too. Alcantara should run you no more than $120 a yard and 2 yards were used on my 2005 sti headliner. Also, riggsbros did the installation for $150 and I wouldn't go back. I got quoted at $75 but they ended up charging me more and took over a week to get it back. Other shops told me it can be done in 1 hour max. Also, they took the top fabric off the headliner before applying the alcantara which caused the middle layer to come off the plastic making certain parts look not as clean as I wanted. So long story short, get the quote in writing if you go there and make sure to tell them just to apply the alcantara on the stock fabric.
