That does sound like a lower budget for the coverage you're looking for...but your location/market will also play a part.
There will certainly be plenty of people who will do it for that price, but the quality is much more likely to be hit and miss.
My suggestion is to do as much research as you can. Look at lots of photographer's web sites. Don't just look at price, but look for styles that you like. When you narrow it down to a few photographers, contact them...maybe meet in person. Let them give you their 'sales pitch' but always keep in mind that this is an interview and you're the one making the decision.
Ask for referrals and follow up on them.
As for questions you should ask...most everything should be laid out in their contract. A good contract will protect you as well as them. If they don't have a contract, beware.
Ask what would happen if they couldn't show up on the day (emergency etc.) Ask what type of backup equipment and plans they have in place...in case something breaks or goes wrong.
Lastly, as a photograph myself...I'll suggest that you really evaluate your wedding budget and see if you can free up some more money for the photography. I think that people often put too much emphasis on how much they spend on the dress, the decorations, the cake, the band/DJ, the reception hall and the catering. While all of those things are important, they are only used/seen for one day. The photos will be your lasting memory of your wedding...so consider that when choosing how much you can spend.
