No photographer will want to release and unedited and unretouched full size photos to anyone ... even a magazine.
But if they are not "tethered" to a computer so you can see them the day of the shoot (as Kimair said), they will give you a proof sheet ... smaller images all printed on a sheet ... or nowadays, more likely a CD with low resolution images .. to use for selecting the finals. Then, he will have to work on those images selected.
So, I think that about 3 days is reasonable for proofs. Probably the best way to talk to him about it is to just ask him what his turnaround time for proofs will be ... and negotiate from there, if you need them faster. Then get it in writing ....
