anyone know who can install and customize Ubersmith? I need to integrate GoogleCheckout, order form, remote reboot, etc into Ubersmith Pro.

You may want to try the employment forum for some better luck. I am sure that Ubersmith most likely provides some setup instructions but i've also heard that the actual setup can be a nightmare :-/

Remote Reboot is part of Ubersmith DE. I doubt it will be easy to ass this to Pro as they would want you to use the DE version for this.

Does pro not have any order form system? I spent a great deal of time building orders form in Ubersmith DE and it is a royal pain to work with.

You might want to contact them directly about a google checkout module as they usually seem to implement features based on customer demand. There may be others also wanting this and asking for it will help the demand.
