The best solution is to do it yourself, if you are fit and capable because there is nothing technically challenging about repairing them. And these days there are such good products on the market like Bitumend Coldmix you can't go wrong.
Clean out the pothole of any loose debris and remove any loose asphalt that has cracked around the hole.
Pour the contents of the 20kg bag into the hole, level with the back side of a rake, leaving a crown in the middle of the pile of asphalt (not big - say 10mm)
Compact - if the repair is small - drive over it your car or use the end of a 4x4 post. If the area is large, you can look at hiring a compactor, but that is added cost and time. Improvise.
The big DON'T
Don't stationary turning on your asphalt - you shouldn't do that ever - especially while the coldmix is curing - this can talk a month during summer and longer in winter
