If I had to do it to get paid I might try this style. Success relies on any wire you might contact being pushed out of the way. If you have a simple plasterboard wall on wooden stud then you could use a plastic version of these. A complicated plasterboard wall would be one with foil backing on metal studs, the plastic ones don't cope well with that.
There are plenty of ways to do what you want to do if you depth stop your drill etc. but that's all more tools and skills than it sounds like you have.
A DIY question from someone not very DIY minded... I need to attach a set of coat hooks to a wall that I can't drill into because there's loads of cables behind it. Any suggestions? Needs to be able to hold dog lead, a towel and a couple of coats I suppose.
