Routing a Battery Box hole?

[V4lve]

Hi.

Thinking about putting a battery box in my OLP. Already active but the battery is currently under the pickguard. Was wondering about who would do it round here (Bath) and rough cost (bass only cost 100 quid so don't want to spend to much).

Have a look at the luthier list here - Frank Aust (Bath side of Bristol?) springs to mind, but I'd expect it to cost £30-40 to do well, so may not be worth the expense?
