Sleek and professional logo wanted for a new up and coming consultant

‘Integris Group Services’ or ‘IGS’

My business provides consulting services to businesses who need help to improve their internal processes and quality assurance - helping them to meet their legal, international standard and customer requirements. I put in place the processes and control points including their business management systems, writing their processes, developing documents & forms and training staff into the new processes. I also help my clients to prepare for audits and accompany them through audits ensuring that the audit helps the client to improve.
Unlike other consultants, I do the heavy thinking and legwork for my clients; providing a service that contributes real value to them - sometimes even helping them to become compliant and avoid fines.
I service many different industries, and all of my clients continue to come back to me because of my integrity, loyalty, quality of my work, determination and commitment to their success.

I’m after a trustworthy and professional look that emanate a brand similar to those of Deloitte and PWC for instance.
The logo can say Integris Group Services or IGS; but I would also like to be able to include acronyms like P&C or HR into the logo at a later stage.
