Logistics of decorating

My wedding is small and casual and most of our vendors are people we know personally meaning a day of planner really isn't necessary. What I do need is just someone to just out up the decorations. I plan to buy all the supplies and just plan to hand someone the supplies to have them put them up the day of. How much should I expect to pay for this and how do I go about finding someone that will just be ok with putting up decor and nothing else?
Or if someone else has had a similar situation and took a different approach I'd love to hear any suggestions (with the exception of asking my bridesmaids or guests to help)
