The cost to repair potholes

Now that it is spring, we have about 20 potholes of various sizes to repair in our community’s asphalt roads. The average size is about 2 sq-ft with some as big as 8 sq-ft. The current plan is to hire a local contractor to complete the project, including all equipment, material and labor for: cutting out the damage, cleaning, filling, tapping, and job cleanup. It would be most appreciated if some of the experienced forum-users provide approximate costs to complete such repairs. Also, any tips for getting the job done right would be nice too.
