Installation of 4 ceiling light fixture + wiring

If the bed room is existing the code would require a switched receptacle. If your floor lamp was controlled by a switched receptacle you would normally use the switch to supply the new ceiling light outlet and splice the feed through so the switched receptacle would be energize all the time like the rest of the receptacles. If the switch is on an interior wall there is no insulation to deal with and if you have attic space available and a craw hole close by it should not take more than ten hours to install a ceiling light outlet. If attic space is limited and crawl hole along ways away then twelve to fourteen hours. Add travel time to and from the shop and additional labor depending on the type of fixture (flush cans or surface mounted). If your fixtures are surface and require assembly then there would be additional time for that. I don't think the seventeen hours is far off depending on the conditions. Since it was four rooms it may have actually be faster to use one electrician with an apprentice so one could be in the attic and one in the room.
