Im not sure where you can do Rahu Puja in Pune. However I can suggest you some great remedies that you can do and get the benefits.
1. Read Hanuman Chalisa Daily
2. Give food to the birds once a day.
3. As your moon Mahadasha is going on Keep fast on Mondays.
You do these remedies and you will start getting good results.
