Going to give you some advise that comes from playing this game all my life. Best I ever scored was an 81, but when I play often I am a consistent ball striker. So take it all with a grain of salt and do your own research. Oh I don't cheat either. : )
First rule of business, there are no shortcuts in this game. So please find you a pro that stresses fundamentals, build a foundation, then work from there.
Now comes the equipment. You can't learn the fundamentals with "improvement" clubs. Most of us start with the dreaded slice, but with practice we learn to swing properly and at some point learn to even draw the ball. Buying a club with 2 degrees of closed face will only work temporarily. If you don't correct a slice with your swing, eventually you will be slicing with that "improvement" 2 degree closed offset club. You don't want to be that guy so don't waste your money on that.
You can find pro line used older sets online for $150 or less in good/playable condition. But honestly I would even suggest picking up a nice 5 & 7 or 8 iron for less than 50 dollars shipped. No joke, that is all you need to learn the fundamentals. Learn to hit those clubs consistenly with a proper swing and then you can think about a full set.
Please, stay away from club fitters. I didn't miss out qualifying for the tour because I picked the wrong clubs, and neither did anyone else. And telling a clubfitter you have $500 to spend is like telling a car salesman how much you can spend monthly on a car.
Do your own research and practice practice practice.
