Create a new logo for a private Ambulance Service

I own and run a private ambulance service in the south coast working for NHS trusts, private clients and hospital providing emergency response services, training, consultancy and work with some local voluntary/charity groups among other services.

We are looking for a professional yet stylish logo with our company name incorporated within it as well as the star of life. We have a rough idea but are happy to allow the creator some creative flexibility.

This logo will be seen by the public, patients, NHS trusts, hospitals and other VIP's so must be of good quality, previous examples of work but be able to be produced.
