Looking at your original post, you want the following attributes out of your stash:
1) A way to be collegial with the other CFA's, who will of course be constantly mooching from your humidor.
2) A way to be hospitable to your clients who smoke cigars, or others who will try an offered cigar but don't smoke often.
Your price range admits a LOT of sticks. Apply a strategy to purchasing them.
1) Buy a very nice, discreet looking but classy desktop humidor. Something that goes with your office. No colors and no flash; tone-on-tone inlay is fine. You've seen The Godfather, note the very small, expensive desktop humidor on Don Corleone's desk. Poor conditions makes a good cigar smoke badly. Make sure this one is always full, too, and stock it from a file-cabinet humidor or cigar store regularly. Like daily. A full humi is welcoming; a picked-over one is offputting.
2) Stock with a variety of smokes. Your criteria are a) mild to medium flavor and b) superlative appearance. Again, no flash, but you want absolutely flawless wrappers and good-looking bands. Good candidates are Montecristo white, CAO Gold, any Ashtons, Fuente, Torano 1916, Gispert natural and maduro. The Monte and Ashtons are more expensive, CAO and Torano middle of the road, Gispert lower, but all are good in that they aren't ostentatious but are good midday to evening smokes. Remember: the hospitality is MUCH MUCH more important than the stick. (Pepin and Padron, by contrast, are not good choices - too powerful in the first case and too ugly in the second).
3) Do I need to mention that you need a very nice, discreet cutter and lighter too? And buy two, because they have the habit of walking off, and you never want to be caught short.
4) If you have more than a few big clients who smoke cigars regularly, suck it up and buy a box of classic ISOMs. My sugestion is Monte #2. They are instantly recognizable as a top-name cuban and have a smooth, flavorful smoke that won't overpower someone at midday. Even if someone isn't a Monte lover (sacriledge!) they will note and appreciate the extra effort made on their behalf.
5) Sizes - notably consistency of size - are also important. Consider your client base. A petit corona sends the wrong message. A churchill or presidente may also send the wrong message, that of ostentation (after all, your client fees are buying the cigars). Robustos/rothchilds are good and a common vitola.
Remember again: the hospitality is more important than the stick. You deliver discretion, quality service, attention to detail. Your humi delivers discretion, quality service, attention to detail.
