Interior doors

I’d like to replace my hollow interior doors and have received a quote from Home Depot for solid, pre-hung doors (I understand the fit/higher labor risk with slab). The quote was $800 including labor for 8 doors, close to $1000 for 5 doors. Does that seem right? Quote was for Jeld -wen, rep is checking other mfr but thinks it’ll be close in price. Any opinions?
