Hello Rummy,
I operate a Mobile Spray Tanning business. At the end of the day, I had to do the "number crunching" in relation to solution expenses, vehicle running costs and maintenance, vehicle
insurance etc etc etc. My price is fair and what I consider to be a good profit. The best advice I have learnt in business is, don't get too caught up in what everyone else is doing...get caught up with what you are doing. Customer service that is consistent and of high standards will be the best free advertising tool you could ever wish for. By looking after them, they will help you grow your business and it won't cost you a cent!
I am only assuming that you are from USA/Canada, so I am unable to give advice on
liability insurances etc etc. Just do all your homework and I hope your wife and yourself will have success!
