Hi Apollon
There is no easy way to get low cost heli time unless you are very lucky a way i did was to get one or to friends to want site seeing trips or take friends for a present but the only legal way of doing this was for them to pay the cost of the heli and you log the time you cannot charge for it but you get the time.
i would however point out that as you are low time doing this you may be asked to do things that you dont have the experiace level required to do it. (please dont take offence i am still low time my self) also try to get in with your flying school and see if you can bum the odd ride otherwise the only way is like the rest of use have had to do is pay for it .
so mate but its not that easy i am affraid.
sincerely
