Scooters can be rented for ₹250 a day. Anywhere and everywhere you will find people trying to rent you their scooter. If you like a bike, a 350 cc Enfield would cost you ₹500 a day (kick starting one of these can be an experience, learn how to do it from the owner if you want to rent one. The recoil from the kick can break your leg). This is the best way to see Goa, you can go where ever you want. And getting around is easy, locals are very helpful just pull over and ask someone.
In case of a taxi, going anyplace, the taxi drivers will start quoting from ₹250 to ₹400. You must bargain.
