What type of stuff are you interested in ? I'm looking for people to help with mobile app dev and could consider remote applicants. Have a look: http://getapony.com/job.html
Not OP but am in a similar position. I had a look at your website and would love to help out with developing the Android app. I'm looking for 1-2 days a week while I'm a student, is this suitable? Once I finish my exams in a few weeks I can send you my CV. Also I'm in commutable distance to your Hatton Garden offices.
