Modify openwrt luci interface

Need someone to modify the luci interface options in openwrt. -Need all options removed, leaving only the Network options. -In Network, remove Diagnostics and Firewall options. There is no need for a firewall on this router. -In Interfaces, remove option to 'Add new interface'. -The router will only ever be a dhcp client so no need for dhcp server options. -The router, when dual port, should give the user the option to bridge the physical interfaces, LAN port connected to LAN side and WAN port connected to upstream router/firewall. No need for this if user wants to use the device as a wireless client. -No admin functions what so ever should be offered via the luci interface. All admin functions remain using ssh only. Finally, I'd like to make this a single page with my own image rather than the menu page offered in luci. Not much else. As far as I can tell, this is 2-4hrs of work at most.
