Re: Detailing business
Plan on spending about $5,000 on the low side of things to start (not including many things)... are you going to be mobile? if so are you going to use people's water and electricity? Whichever products you decide to with, my suggestion is to buy in bulk (at least 1 gallon) and buy empty bottles to fill. Couple helpful things not mentioned.... polishers, air compressor, some kind of carpet cleaner (steamer, hot water extractor,etc.). Trailer would be a nice idea. Instead of buying a pre-made one, you can always piece it together... however you will end up spending about $2000on the trailer, water tank, tool boxes, power washer.
Big tip,if you do go mobile, and want to get a water tank with a pressure washer, make sure your pressure washer has a self priming pump, and is capable of pulling water from a static source.
Also, get some insurance and business license, the last thing you want is dropping something on a customer's cars and have to pay for a repaint, and when you can't afford it and your customer's sues you and you have no license, it just does not work well.
