I have a single-stage press as well (for now; I'll probably get the Lee Turret Press sometime this year). Anyway, here's what I do:
1) Tumble brass upon returning from the range (including range pick-ups). I do this with a mixture of about 2/3 walnut for cleaning and 1/3 corn for polishing. I do this for 3-4 hours. I don't count the time for this, since I can do about 600 9mm and 450 .45 cases in about 2-3 minutes - to dump them in, then pour in the media, then flick the switch, then come back and separate the media from the cases.
2) Deprime and size. I do this in batches. For 9mm and .45, which I shoot more than anything else, I'll wait until I've got several hundred. I'll oftentimes do this on a Lee handpress, because I can do it inside while watching TV (esp. my wife's crappy tear-jerker chick flicks on Lifetime, when I have no desire to pay attention). I can do about 8-10/minute, if I really want to do it quickly. I don't lube, as my dies are carbide. For 1,000 cases, this will take 100-125 minutes.
3) Bell the cases - this can also be done on the handpress. Similar to the deprime & size function, I can do about 10/minute. Time: 100 minutes.
4) Priming - I use a Lee Handprime tool. This is pretty quick, 12-15/minute. Time: 67-83 minutes.
I will then stick the sized, belled and primed cases in a container (currently a pretzel barrel with a screw top, good for approx. 2,000 9mm and 1,500 .45), to wait for loading powder and bullets.
5) Loading powder and seating bullets - I do this whenever I've got the time (usually a couple of hours, to maximize efficiency). I will load all of the powder in 50 cases in a reloading tray, then load the bullets and put the loaded ammo in one of the plastic trays you find inside factory ammo boxes (I've got a big box full of them for various calibers - no need to buy those plastic ammo boxes from MTM or whomever). I also measure EVERY round for COAL, and either pull out those which are too short or reseat for those which are too long. Time: powder loading (once you've got your powder dispenser calibrated) 5 minutes per 50, or 100 minutes for 1,000. Seating the bullets takes about 10 minutes per 50 (the measuring slows me down, but the peace of mind is worth it), or 200 minutes for 1,000.
All together, to load 1,000 rounds probably takes about 600 minutes. Yeah, 10 hours. It'll save you a few bucks per 100 rounds for the 9mm (1000 cheap FMJs will cost about $0.04-$0.045 each, the primers are $0.02 each and the powder is under $0.01/round, for a total of about $0.075/round, which gives you a savings of about $4 per 100), but if this was your only use for the press I'd say forget it. Your time probably isn't worth it. Of course, for me the reloading is also about accuracy and cheap therapy (its usually very relaxing, unless I screw up a bunch of rounds), so the dollar savings is not all that there is to consider. For .45, .38s and virtually all rifle rounds, your dollar savings will be considerably higher (as an example, on .45s I can produce rounds for roughly $0.10 each, compared to twice that for Winchester White Box at Chinamart).
I'd do the reloading of the 9mm if I were you ('cuz I do it myself), as a means of making the press pay for itself. Once you've loaded about 600-700 rounds, the dies will have been paid for, and everything after that is gravy. More than anything, though, it depends on what kind of time you have to devote to it. If you're like me and you use otherwise non-productive time to do the basic tasks (deprime/size, belling and priming) so that the actual time out of your life to make the ammo is far less.
