I need a professional logo design

I require a professional logo design based upon my sample design, I would like several variations of my design so I can pick the best option but want to stick with the font and colours I have in places already.
This logo will be used on my website and for print so it must be supplied in different file formats and be of exceptional high quality.
Turn my basic idea into an exceptional brand logo which is for a facilities management company and will be used in the UK nationwide it must project a high profile professional company.
