OP, I've had a hair transplant done. There are many comprehensive forums on hair restoration - I don't think links to other sites are allowed, so I won't post any, but a quick google search will bring them up. The best way to approach your situation is to start reading up on the procedure and the reviews (there's literally 1000's) and see how other people's Before and After photos look. Some of them are amazing transformations, some are fakes, and many are very motivating. Find reviews of people who have had a similar hair loss pattern to yours and see how the transplant has changed their look.
I was procrastinating for years to get a transplant done, and it was the fear of the pain that stopped me. In reality, it is not painful at all. I actually fell asleep during the procedure, and apparently that's quite common. The best doctors seem to be in Belgium (and that's where I went). They are not cheap however. Turkey is a cheaper option, but you have to be careful there - there are literally hundreds of back-alley 'doctors' who do this (it's an un-regulated industry). If going to Turkey, then pick one of the top name doctors (Cinik, Ergodan etc), but be aware that the doctor will have literally 5-10 other patients in the same day and will let his technicians do the actual work whilst he comes in and out of each room inspecting things. Turkey is about a third of the price as the Belgian doctors. The other option is India. I don't recommend British doctors - and certainly anyone with a Harley St address should be avoided.
You can figure out roughly where you are on the Norwood scale by looking at online guides. This will give you an indication of how many grafts you will need, and hence the cost. If you are a Norwood 4 or greater, then you probably need 2 transplants (like me). Then email a handful of doctors - most have online forms with photo attachment option and they will access you with an initial description of what is required and how much it will cost. Take it from there.
I'm glad I had mine done.
Good luck.
PS - with scientific advances, nowadays, going bald is no longer compulsory.
