Changing Strata Managers

We reside in a new complex of 12 Town Houses. The Strata management team seems to have been appointed by the developers and not the owners. I am on the committee of 3 and the Strata manager appears to only contact and deal with one Committee member and does not reply to emails or return calls from me. One of the owners called a meeting with the committee to air their greivances about the committees inaction ( which is fair enough) and the committee has decided to dissolve and all problems are to be directed to the Strata Manager. In the meantime we are going to start to look around for a new company to manage us. Can anyone advise what is the best way to go through this process.
