I might cry

Depends on what you are getting.

For a long block, the local guy here could do it for around 3K and it's a solid piece. Probably have a Comp cams xe hydraulic, KB's, all machining and a rebuilt set of heads.

For 7K I'd expect at least a stroker with aluminum heads.

Are you providing cores for the build or is he getting everything together? That's a crazy price... run run run!
