Swapping over from gas to induction cooktop - who do I get in?

I currently have a gas stove installed, but am swapping over to an induction cooktop instead. I've ordered the cooktop, but I'm unsure on where to start with getting someone in to install it. Will I need to organise to get the gas disconnected separately, or is it common for tradies to have both tickets so I only have to get one person in for the job?

I'd love to get some quotes on adding in a few extra wall sockets too, so hoping that it is possible for everything to be done all by one person - and preferably before Feb when baby is due!

TIA for any suggestions on who to contact :)
