Would like to create/add onto my current site a system where church templates are offered for different churches. They will pick template and provide minor customization (putting name on church etc)

I have purchased some templates from http://www.christiantemplatesonline.com/joomla-cms-templates.php

(so I have all the files/graphics/etc for about 10 different joomla templates)

Once a organization picks their template/site we will customize and host on our server but they would be able to add through their own admnin (substance (calendar events/contact/info about different ministries)

There is a set up that is used by a group called http://www.adventistchurchconnect.com/index.php that provide all Seventh-day Adventist churches with their own site and offer different options. etc.

I can get access to view the admin set up for one of these church websites so you can see in more detail how the admin is set up.

I would like it to run very similar to how they have it but cater to the different churches other than Seventh-day Adventist since they already use their in home system for their own sites.

So I will need set up of the joomla templates so that I can have full functioning websites do show customers examples.

I will also need a site set up somewhat like the adventistchurch connect where all sites are hosted on our servers but they have access to their specific churches to make changes.

Hope this somewhat clear if not let me know if further explanation is needed.

Thanks
