Being in similar position I'd say if you want to earn London rates you'll have to move to London. There is a reason why companies in London hire people from Europe and that's because they won't be paid London wages... Having said that you will see much less money staying in your pocket once you move to London, it's horribly expensive city. And if you have family it becomes even more expensive.. People do earn a lot when they find a niche - in example trading software. There is lots of money in trading (i.e. Forex) and trading software which is low latency type of software. If you go mainstream you will earn what mainstream earns, think outside of the box. From another perspective in the very moment you start specialising you might find yourself out of work when your niche disappears. So it's always a chase for holy grail and there is none - take risk, invest your time, be different and you'll get paid more :-)
