Horse Grooming Supplies

I am new in the horse boarding business. I am getting my first customer who is going to board a 3 year old gelding with me. I don't really have any experience with boarding or grooming horses, but have fed horses before and I really love them. What do I need to do and what do I need to get to make this horse boarding like all other small horse boarders? ( what to charge, etc.) This is a family friend who is allowing me to take care of his horse, so I know some of you will say " you really should have experience of working with horses, before you actually get in the business." i know, but this is for me to get the hang of it, im only doing this one until i can handle others. so please i am just asking what supplies do i need , including feeding troughs, and how much do i charge for this one boarding. all i am told to do buy customer is put him in a stall at night , feed him, clean his stall everyday, let him in pasture everyday. i live in minnesota if it helps out with an estimate.
