New name for my business

I run a small security compliance training company based in Walthamstow, east London running for approximately one year which trains people to obtain a security qualification and then go on to apply for an security industry authority (SIA) licence which is a legal requirement for a career in the security industry. The unique selling point is that I help the people we train to find work after they have trained with me. This may be through CV building and advice as to where to look for work. I try to deliver after course support. At the moment I am working as a department of a security company (Double Check Security Group) so we have managed to employ some of the people we have trained. I am branching out and going alone while maintaining links with Double Check Security so that they can continue to recruit people I train. I am currently trading under the name ‘Double Check Security Training’. As I am branching out I need a good name for the company.
This is the only marketing we have at the moment - it has worked well we have trained roughly 400 people in a year but I really want to take things forward by developing a good name, brand, website and additional marketing to grow the business. For now though I just need a good company name
