I have tried punting in various parts and cities in Indonesia.
Jakarta is now becoming expensive due to economic boom in Indonesia and also partly because of tourist and businessmen from neighboring countries who spoil the price.
Nowadays there are already a lot of modern massages, Karaokes, Spa clubs designed exclusively to cater Japanese, Taiwanese, Singaporean businessmen. But if compared to UK certainly is still less expensive, certainly.
In my opinion, the best place for punting vfm WGs in Indonesia is in Surabaya, east Java. There are a many budget flights from Jakarta to Surabaya or from Bali every day. In Surabaya last year you could still get a WGs for less than US$20 an hour.
In dolly area for instance, there are a lot of WGs in the fishbowl below this price range.
But some people like me are more into Leggy, blond, possibly blue eyes, which is almost impossible to find it in Indonesia. But a little bit desk and leg work people could still find gem for less than US$20 an hour.
