The best way to make $1,000,000 is to start with $2,000,000. Seriously, tracks do NOT make money. You have two choices from my perspective: Own the property the track sits on - and have enough space to have at least a small hobby shop, and several rental spaces (strip mall) generating cash flow to cover the majority of your expenses.
Or, have a multi-use facility much like the new track in Phoenix at Speedworld.
3000sq ft is not near big enough for a small track much less a large one. 50' x 60'? A big track is like The Farm II, which is about 150' x 250'. My club's track is 140' x 80', so to have that track indoors would require AT LEAST 15,000sq ft. Plus room for pits, storage, RD/computer stand, drivers stand...
Then there's the pesky matter of a business licence, insurance, city codes (you're going to be making a lot of noise, generating traffic, too many things to list), parking, ventilation & EPA concerns.... You'll need an attorny for a lot of this crap.
Good Luck!!!
