In a guitar shop, roughly how much should I be charged for these services?

1) Pickup swap and new electronics put in

2) Your Guitar set up

If you cannot tell me how much it usually costs, could you tell me how much you have been charged in the past for having either of those two services?

Learn to set up your own guitar, it's fairly simple (although you could get really complex if you start replacing the nut and custom making your own, etc) and it's a good skill to learn. The pickup swapping is possibly even more simple, you'll just need some basic soldering skills (you can buy a soldering iron for fairly cheap) and then you can just buy the pickups and that will be the cost.
i dont live in the UK, but it cost me 80 (USD) total for 2 humbuckers swapped, guitar setup and a bridge repair
