I got some time to spare,
so I'll explained how I do it.... (I used to do some freelance)
----------------------------
after discussion with the client and got all the necessary infos..
ask 50% before doing anything...
-----------------------
1st
start modeling, texturing.....etc.
interior for 1 area, for me took from scratch to final render & touch-up, about 2 days / or 1 whole day (if I don't sleep.. well.. I rarely sleep for days.)
for exterior 2-3 days.
render is really not a problem, with the right settings, for a high-resolution image the longest time it takes is around 1 hour.
I use 2 pc, 1 for render and other one for work (sometimes render when I'm not using it).
--------------------------
2nd give the client a preview
-for a preview I do a 6 angle camera shots, brought into photoshop and combine all into 1 big image and email to them in jpg.
(no compositing in photoshop whatsoever.... just a normal low-res render.)
low-res render (1000 x 750) x 6 (camera shots) per area
---------------------
3rd (estimated time, 1-2 days)
high-res version (5000 x 3750) x 1 (selected angle from client) per area
usually at this stage I rendered the visual and do some touch-up & compositing in photoshop,
for example, an exterior render of a new shopping complex, in photoshop I put some real people, sky, cars, plants (landscaping)... etc.
skip unnecessary modeling for anything you can do in photoshop, those extra polygons = extra render time (and sometimes won't even render).
-------------------
4th
second preview. email them the final look (but low quality resolution)
when got an A-okay from the client,
next step :
done. ask the remaining payment before giving the final product. (no money no talk.)
if not, do some correction/alteration... changing idea..? thats gonna cost extra.. (first changes is free)
-----------------
well.... different people, different way of doing stuff..
about the payment,
usually I gave them the base price for the service (modeling, compositing..etc) (not including render per piece, that's another price.)
I don't charge according to how many hours/days, and I rarely charge them base on complexity cause I always do my best even for a simple job.
(I hate doing a half-4ss job)
if they say.. "wahhliau weyyy... damn expensive mehh...?"
if that happens, most of the time, I just ask them what's their budget, and we go from there.
(you can always decline the work though.)
wahsaiii... long post already.
anyway, good luck in your job.
