Anteksi, minä en puhu hyvää suomea. So I have to ask in english.

I have got my car to pre-registration inspection and got feedback that it is in overall good condition, however still a few things need to be repaired.
1. There is a leak in a power stearing system (just behind the engine in a lefthand (drivers) side). Hope for some gasket or pipe, but never know.
2. Airbag fault.
3. Light adjustment. (It's too low, will fix myself).
What would be recommended service point to visit in terms of client-pocket friendliness (read: not too costly)? I am located in Espoo, so Espoo / Helsinki and most likely Vantaa area would do.
Thanks in advance.
