I would like to start my own errand running/delivery business. I will be using my own 4 door economy car so I won't be able to deliver anything super large. What should I charge people for this? Of course I know I should charge less than any of the regular commercial business' out there. I want to make it very affordable so I can attract customers but would like to make at least a small profit. Any thoughts on this would be greatly appreciated. Thanks so much in advance.
