For that amount, chances of getting a good site is meager. It is better off having a good budget or getting quality links for free.
You can start a thread here and give your price all sites owner will contact you then you can choose good sites.
I have an acquaintance who does backlinking for 15$: - 250 high PR links with some anchor text in first layer and around 2500 profiles with links to high PR links for second layer OR - a bit more than 5200 backlinks as user profiles with your URL and up to 3 keywords This is all done in 1-3 day deadline (most of the time in 24 hrs) and you get a full list of all links he creates so you can check them yourselves. My other friend tried the second service and I random checked his links (I don't like to recommend my friends to people if I am not sure they do their job right), and it was really done well. So here it is - a recommendation. If you are interested, send me a PM. The only thing is - payment is in advance OR 8$ downpayment, 7$ when the job is done.
