On a Budget - Rock Climbing and Yoga weekend in Italy

Details
Hi guys, I'm organising a Climbing and Yoga weekend in Tuscany. A nice way for locals and foreigners to meet and exchange experiences, culture, language while rock climbing.
Accommodation: my house (if you are picky, and have a problem with sharing rooms, bathrooms or camping in the living room - there are many hostels, b&b, Airbnb and hotels in the area). My place is obviously free.
Food: I'll do a shopping and prepare breakfast and lunch (shopping budget per person for the weekend 10€) - dinners at pizzerias or restaurants (price range between 15€ to 25€ per meal)
Climbing and yoga: instructor, mountaineering guides and gear will cost 105€ per person for the weekend.
We'll climb all Saturday and Sunday. Yoga after climbing to restore.
Destination airport: PISA
transfer from Pisa is between 2 and 5€ with bus or train. if you arrive late I can pick you up at the airport (that will cost 20€ for fuel and highway)
