I'm sure it varies from city to city; so I will go with what I know. In San Antonio, TX and there abouts, we normally hire by the half day or full day. If it is a weekly job you should expect to pay $65 - $75 for as half day and $110 - $120 for a full day. It would be next to provide lunch and it builds good will.
If it is a one time job, I would expect the prices to be higher.
