With that structure it's pretty much a crapshoot, by the time 4 people have gone out the blinds are 80-160!!! At five people they are bigger than the starting stack.
Your best strategy is to get dealt some really good cards.
Failing that push all your chips in every time you get dealt something pretty (two face cards, any pair, A8+). There's not a lot of chance of skill playing much of a factor with that structure I'm afraid, good luck
