Was quoted $1250 to install a chandelier. Job was to 'remove existing chandelier, reinforce the electrical box for power, reinforce 2 mounting locations for chandelier, drywall patch and texture, and 2 technicians.'
When they came out they sent one technician (who was at least very friendly and helpful) and he only needed to install 8 drywall screws and hang the chandelier. No 'reinforcing', drywall work, electrical box work, etc.
When I complained about the cost (>$400 / hr to hang a chandelier), they dropped the price to $1000. When I complained further, $950 was 'the lowest they could go'.
Make sure both parties fully understand the work required beforehand and agree on pricing because if you don't, they will screw you in the end.
