I am going to move to Tehran in a few weeks time.
I am not sure if you can find any answer from Iran society if there is one.
Better to go there and try to search the places yourself. Sure you will find someone helpful on the road there. A lot of good people there on their small M/Cs.
Pitty I can't import my bike over there... and it is not good idea to ride a bike in crazy traffic jam of Tehran
