Upgrade V4.02 - V4.06

Hi Folks,

Does anyone know how much an upgrade from esvon 4.02 to 4.06 would cost approx. I would have to get Esvon to do the upgrade as i have previous customisation done by Esvon. I have just tried Esvon 4.06 on a test server and it is really nice. Ajax Regions and Dependant Dropdowns. Some very nice features indeed.
