Network Design Consultant

Can anyone here recommend an individual or company who would analyze a
working network design from head to toe, suggesting changes and improvements
where needed. This would include overall design from a high level but also
analyze actual router/switch config's. Looking for someone/somecompany who
is not vendor specific, and experienced with high performance, redundant
networks.

Please respond offlist. I am happy to summarize for anyone interested.
