Personally I don't think it will be enough. one advice tho. Fro my experience with fb ads, they suck hardcore. Bing ads, they're alright but you need more then 300 $ to find something good, but then again if you have good ideas and you do enough research it MIGHT be enough to find something. Adwords ... to expensive. Also have a look at stuff like directCPV , trafficVence ( 1 K deposit needed tho ) and so on.
