Cheapest option for a couple of small dents is to pay a PDR tech. Not as easy to use as the youtube videos would lead you to believe & it's very easy to push just a little too hard & split the paint.
seriously though I'd highly recommend a PDR for just a couple of small dents - it's dead cheap and minimal chance of your car ending up like Father Ted's.
