Actually this is the time to start looking for deals. Newegg has a pioneer vsx 1022 receiver with your requirements on sale right now. A blu-ray player is not going to run you much either with all the pre and black friday sales going on. The hardest part will be speakers that will be sufficient for that large of a room. Stay on top of the sales and you may be able to come close.
If you're able to do in-ceiling speakers for your room, some of the products from Monoprice work quite well. With some careful research, you can come in right around that $1K pricepoint. A BR player can be had for $100 these days, if not less, so your receiver is going to be where the issue most likely comes into play (provided you don't go with actual loudspeakers). I've always had good luck with Onkyo products. They're packed full of feautres for the price you typically pay.
