What costs are there for owning your car wash business? -

Im doing a project on starting a car wash and i need to do the break even point on it and need the costs. I know there is rent, water, supplies (i guess water is supplies), employees, and what esle?

if you do a self serve car wash - Equipment prices are 1/100th of the cost of a full service car wash - or less and no employees neededa change machine that you need to refill daily and empty out the coin boxeselectricity - maybe gas for if you have hot wax or hot water washing
