Same here. Just finished a dodger
. Material alone (retail prices bought by us) cost ~$1800USD for 3 sheets
of Strataglass, 16yds of Weblon (used instead of Sunbrella), a spool of Tenara thread, grommets and snaps, zippers, etc. We are lucky and labor here in Guatemala
is inexpensive - we had one of the best/most expensive places charge us $350 total in labor. We did pay extra for shipping
the materials in.
Call it just north of $2k. The original one done in the US was over $4,000.
All-in-all, I don't think your quote is unusual.
Your pain will be in discovering that much of the Sunbrella you pay for (or whatever you use) will be left on the floor as scraps. You pay for both the window vinyl and the Sunbrella missing from those windows!
Of our 16yds of Weblon, we have maybe 1yd of remaining material left in the dodger!
