Have you been playing USTA tourneys to get your national rank up?
It wouldn't hurt to play a few Nationals, and sectional champs to bolster your top 500 list position so that you will be accepted into the qualifying draws.
It would be silly to travel to futures without a national ranking and possibly get turned down because the draw is full.
It is usually a two year process to play the circuit.
You either die a hero or live long enough to see yourself become the villain.
