Thank you in advance.

In fact, given Luis Rosales suggestion to do "a looooooooong molecular dynamics", you could use normal mode analysis as a fast tool to obtain different conformations of your protein. Our NMA web server ElNemo
http://igs-server.cnrs-mrs.fr/elnemo/
allows you to generate normal mode perturbed states of your protein (i.e. look ate the "example" page). We have shown this to be a way to solve difficult molecular replacement problems in X-ray crystallography (if that is what you need the models for).
Kind regards, Karsten.
