Welcome to RC India
Unless you want to throw away
10K, please do spend some time reading the existing threads here on starting with RC. Specifically, you will crash the heli the first time around, unless you train yourself using simulator software on a computer. Secondly, there are two categories people go for. One is sort of toy grade, which are low cost ready-to-fly (RTF) combinations with the heli, radio and everything else needed to fly, but these do not last and parts support is next to non-existant. These are low cost (within your budget), but very few of these are outdoor models. Once the heli breaks, the rest of the stuff pretty much becomes useless.
Or you can spend a bit more, and get a better set that can last longer, with parts support, and you can mix and match the items (get a new heli and use the same radio etc).
Short story, you have got a bit of research to do !
