You're talking about sprinting before you even know how to crawl.

Find a gym, get good enough to spar... see if you'd even be good enough to compete as an amatuer... get a few fights under your belt and only then should you even be thinking about boxing as a career.

And nobody can tell you what style suits you best based off of a forum post.

If you want to find a good gym I'd suggest going to some local boxing shows/tornaments and seeing which gyms are doing best.
