I'll play Devil's advocate here. But I think choosing a carry gun based on how you intend to carry is plumb bass ackwards. First and foremost, you want a reliable firearm that you can shoot well. You need to like shooting the gun and practice with it.
Asking others what's best for you is like asking someone else to pick your wife. What's perfect for them may not work for you at all. The first step is to find the right gun for you. Because if you don't like it, odds are you won't carry it. Only then do you figure out the best way to carry it.
I don't like pocket carry. Once in a while I may stick a J-frame in a coat pocket for a quick trip to the store or something. But there's no way I'd carry in a pants pocket all day long. To me its uncomfortable, awkward, slow and almost impossible to draw from a seated position. And you did mention jeans which pretty much rules out pocket carry by themselves.
I'm not a big fan of IWB either. It does work, I have done it before and might do it again. But for some people it does tend to get uncomfortable after a while and sometimes rubs against your body until your skin gets irritated. The only way to know for sure is to try it. If it doesn't work for you, you've wasted your money on a holster you can't use.
The fact is that most of us who have been carrying for a good while have a box full of holsters that didn't work. 
...
and a few that do!
Since you're on a limited budget, can you really afford to experiment? And if you don't like your holster, chances are you'll leave the gun at home instead of actually carrying it.
Concealed carry is much more about the rig and your attire rather than the gun itself. A good concealment OWB holster and a proper belt makes carrying any gun a whole lot better. It also opens up the choice of gun to a much wider selection. Good gear ain't cheap. But its well worth the cost. Especially if you only have to buy once.
BTW: my usual carry gun is a Commander sized 1911. With a proper belt and holster it conceals just fine under an untucked T-shirt.
