Converting sprinkler heads to drip system - new watering restrictions

Hi all, our municipality now prohibits the use of automated sprinkler heads, but drip systems are ok.

I am told I can convert all the sprinkler heads to feed drip lines. My service says that would cost about CAN$2000, which is out of my budget range right now.

Anyone done this conversion themselves? Was it hard? And are there instructions somewhere I could follow?

Many thanks!
