You have to ignore the odd bitter individual who wants to make fun of others through an anonymous forum. It takes less effort to be helpful and it makes the world a happier place.
It is not that hard to learn to fly if you have some basic aptitude. As advised have a trial lesson. Most people can handle straight & level, slow turns at height but don't be put off when you find that you can't hover strait off. It takes almost everyone a few hours instruction and practice to hold a hover.
Your expectation of time is about right but it could be a little quicker if you are considering taking instruction in a block - flying every day.
You have ground exams in Air Law, Meteorology, Principles of Flight, Navigation, Radio, Human factors. Keep up with the exams as many fall behind here.
When you get your Private license you can fly alone or with others but you can't take any paying work. You would nee a lot more studying, ground exams, and flight exams to get a commercial license. Even after that you would need a number of hours practice before you can take paying work.
There is nothing cooler (my opinion) than piloting a helicopter. Go for it!
