multisites (jms2win) configuration with Joomla

We have several joomla website. We are now trying a new software called [login to view URL] We have problems to use it with different domains. We want to have a master website ([login to view URL]) and several slaves. They will have different domains (like [login to view URL]) and will use the same joomla + template configuration. These websites will have DIFFERENT DATABASE. This, we can do easily. But we have a problem to deploy the configuration with jms2win. We want someone to: 1) Do one like this. (do the slave with same template + same joomla using jms2win) 2) Show us how to do it. We are trying in CPANEL to use "addons domains". We have CPANEL with WHM. It works with apache. But it makes an error saying it's not the same owners, and they are! Something probably needs to be done on the server, to adjust the configuration. Maybe the registar, we don't know! WE NEED TO KNOW HOW TO DO IT, because we might have to repeat on twenty or thirty websites. If the price is good, we can ask you to do that job, after. But again, we still need to know how to do it. So, when you quote, think about the work + the fact that you must write down all steps and tell us the steps.
