^^^If this is really your goal^^^...
Then...IMHO:
-Common sense should prevail.
Wouldn't you agree that it would be prudent to save-up as much as you possibly can?
-At the onset of your legitimate, law-abiding detailing business, you'll probably find that purchasing
the majority of your detailing supplies at the lowest price-points possible (jobber; bulk-sales)
will be of more assistance in enabling your business venture to make a go of it,
than say, more expensive car care products.
(Also:There are insurances, health care, and retirement funds to keep in mind.)
-I may be wrong, though, if you already have several Paul Dalton-style detailing sessions lined up.
Afterall...Only 26 of those jobs per year, for the next ten years in a row,
will net you close to a cool million dollars!!
Bye Bye to Rhode Island then...???
