i've got about 15000 to invest and i want big returns over the next few months. has anyone got any high risk tips?

much appreciated

Please do not think I am being unhelpful but I strongly suggest you Start
in the way I mentioned and call it Hurdle 1.

Good advice from ajren and well worthy of consideration.
Could be worth taking a look at threads by goldfinger, he, at times, seems to have a midas touch specially in the high risk shares you hanker after.
For my own benefit if you dumped your 15k into CYH that would surely push the price up and i could definately do with these heading north over the next week or so !!!
AS ALWAYS DYOR
