Will someone price the wall without charging?
No-charge estimates are advertised by 11 of the 24 companies here. A low wall on firm ground with easy access can be priced from a walk around. Anything tall, anything on a steep slope and anything with a driveway above it needs levels taken and usually an engineer, and that part is design work somebody pays for.
