Here is kind of what it comes down to, being limited in funds:
The cheapest route to go will be to get an HS Precision stock. The basic models (VS or P, and some others) is going to set you back about $300. This is a good alternative because its a drop in fit for your rifle. No bedding required. Take off the old stock, put on the new one, and go to town. There are some nice adjustable HS Stocks also that will run from $400-$500. Many options, most well suited to your 700 VLS barreled action.
The next step would be to go to a McMillan or other quality fiberglass. I love McMillan, great stuff. But there are others also, like Lone Wolf, etc. A good McMillan will set you back about $500 depending on options. if you go with one over their standard models (A1, Win Marksman, etc) with no options on it (like adjustable pieces) it'll be about $400 (give or take). You can shoot these without bedding them, but you will not get the real accuracy out of your rifle unless you do glass bed it. You can do this yourself or you can pay about $70 - $100 to have a smith do it. Could also pillar bed, etc.
