Update branding of company

Industry: Business
Design details: I'm looking to update the branding of my company.

We have been in business for around 5 years and are looking to update our branding. We already have good logo etc. but want to update the 'feel' and appearance to appeal more to our target audience.

We are a health and safety company that has a fun edge which allows us to stand out amongst our many competitors. We need to 'mature' our current branding to something more corporate yet retain some fun.

The branding you create should allow us to replicate the feel across our company stationary, website and vehicles.
Ideas for the visual style: See above
Urls to draw inspiration from: www.positivesafetytraining.co.uk
Where the design will be used: Web, vehicles, leaflets, letterheads etc.
