I dont think London is a good idea at all. So many open jobs, you have to pay a high price to get people to work for you as they usually just pick the highest paying employer.

Currently open jobs by city (had that list anyway so might as well post it)

- London 20
- Belfast 7
- Birmingham 2
- Glasgow 2
- Aberdeen 1
- Norwich 1
- every other city in the UK 0

But OP can probably tell you more about that
