You know, this topic of "Mobile
Spray Tanning" has been beaten to death on this site. What is there really to know? You get a spray unit, put it in the trunk, and drive to peoples houses and have spray parties, like Tupperware® of the next Millennium.
Take a little initiative to do a search on your own and see what you come up with but the sad part is that most seem to just come on here and ask the same stupid question instead of doing a little research first.
That seems to be the problem. This mobile thing seems to cater to the people that think it will be super easy to make tons of money doing it and to the ones that have no balls in putting up large sums of money to do a real business but instead join the "Trunk Slammers Union®" and try to corner the market with buying the cheapest e.quipment, the cheapest solutions, and the bare minimum and call it a business.
Here are a few tips for you, first, do not quit your day job and two, do not go into business with partners or family members and three, don't expect much of an answer with just jumping on here and asking the same old mind numbing questions that have been asked and answered already. It starts to get annoying.
Take your $1,000.00 bucks that you are attempting to start a "business" with and put it in an IRA and go and take a couple of business courses at your local college, research the industry, then decide what you want to do. Not everybody is cut out to run a business and if you are stumbling on the simple stuff then you will be in real trouble when it comes time to support yourself for real.
