Hey FSNet,
First of all...Eraser has given some good information, so I won't touch on what he already mentioned. With a low budget your only option is figure out how to do it on your own.
The biggest problem with your site is it's architecture. The way it was built/developed makes things much more difficult in terms of being properly indexed and eventually ranked.
If this is a long-term/serious business you are trying to develop, I suggest you immediately start planning for a major overhaul as it will either be expensive, or take you a long time to take care of yourself.
Honestly, the more important issue is that your site really doesn't have a lot of quality unique content that is able to be spidered...so even if your site was properly indexed, you still wouldn't receive many rankings - if any.
The "review vertical" is very competitive regarding search rankings and it is loaded with serious bloggers who are constantly adding fresh content. This means you need to do everything possible to help the search engines to determine you deserve to be ranked.
Basically think of it this way...pretend you don't own this site and you were searching on "Search Engine A" for a review on a restaurant in Laughlin, NV.
- How satisfied would you be if you saw this site ranked number 1? Number 10? Number 50?
- How confident would you be that you'd easily find the information you were hoping for that initiated the search?
In my opinion, nobody that is actually capable of delivering results would take on the entire project for under $100k...that should include the new site development, initial optimization, analytics set up, etc. Just as a final FYI...I'd estimate that it would take anywhere from 6-12 months for you to start seeing results (from development to actual natural rankings) regardless of who you work with.
Good Luck!
