I don't mean to sound crass or try to crush your dreams. I played a money open tournament a few weeks ago. I was coming in playing great tennis, crushed a 4.5 at my club that week, so had hopes I could at least get a few games. And, in fact, I did win my first match against a local high school player.
But in the 2nd round, a local junior college player toyed with me before destroying me completely, 6-0, 6-0. And he went on to get destroyed in the next match. And THAT winner got destroyed in the next one by a guy who used to have ATP points. And the former pro then lost in straight sets in the semi's.
And none of these guys would be able to win a futures first round match, or even get through the qualies. Those guys live and breathe tennis, training every day for hours with no other distractions.
So play a lot and progress, and then try your hand at money open tournaments, and you will see what I'm talking about.
