Customizing Boxbilling theme

For my business i need a customized client and admin theme, based on the default boxbilling theme. I will be using the software more like a client manager than a webshop. Client theme - direct login field, no registration feature - logged in dashboard: show tickets and products - remove order functionality completely - remove pay feature - remove payment history Admin theme - add the functionality to add products to clients manually - remove payment gateways - remove domain registration - rename 'Hosting plans and servers' - rename options within 'hosting plans and servers' You can find more info about boxbilling: [login to view URL] and [login to view URL]
