I would reserve some of your budget for the possibility of needing or wanting a new cartridge.
Look for a speaker that is reasonably sensitive (85+dB) and does not drop below 4 ohms impedance. Therefore most 50-100 watt amplifiers will serve, given your room size. There are many integrated amplifiers having a retail price of $1500-$2000 that would fit your budget. Likely could be purchased at less than retail.
When shopping for speakers consider the amplifier driving them. If you purchase an amplifier 1st, take it to auditions.
I agree with noromance, you may not have to max out your budget to find yourself with a very pleasing system for your office.
