I honestly thought this thread was a confessional about gambling away the money you intended for buying a new couch and are seeking help with your compulsive gambling.
Needless to say, I was greatly dissapointed when it hit me what it's actually about. Oh well, on to the actual point of the thread.
Coaching is a good thing, but many will agree that it's very expensive, which is why you should try and exhaust all of the free and cheap knowledge sources you can get your hands on, and there's quite a bit of them. Once you're done with that, gauge how much you've improved and then decide on getting a coach or not.
The first thing I'd suggest to you is hitting up our very own Golden Archive here on the forums. It's in the General Poker section. Spending a week or two there studying the threads will no doubt help your game immensly. Of course after that you can move on to the various video material on youtube, free e-books from various pros (Doyle Brunson's Super System is a must read even if it is a bit dated), and of course there may be some cheap poker books
you can buy in bookstores where you live.
Focus on getting as much as you possibly can out of all of those free sources, and then try coaching. Who knows, if you study carefully you might get so good at the game you'll be able to pay off your lessons with the money you made on your road to getting better with the free stuff.
