Why not. Loving this friendly community, my apologies for not being as familiar to forums as you are.
Alright, i'll try to explain whats going on. You started by asking an acceptable question. Where you went wrong was asking question after question that you could have easily answered yourself. I quit using HB just under a year ago and recently started using HB again. A lot has changed(paid plugins being on of them), but i was able to have HB up and running smoothly without asking a single question. Why? Not because i have some skill or ability that you don't, its because i browsed the forum looking at posts and guides as well as using the search function. Your current question is 'what profession is good for making money?'. You can easily make that decision on your own by using google. At the moment I have one character with herb/mining at 525, this makes me a VERY good chunk of gold. However i decided to do a little research to figure out what would compliment these two skills well, i came up with Jewelcrafting and either Enchanting, Alchemy or Inscription... I'm not going to detail all my reasonings or methods of making money with these professions, but that should be enough information for you to start googling and coming up with some sort of game plan.
