Look in one of the Pro groups or Custom Installer forums for someone in your area to set you up.

Otherwise, for a current product you're looking at Harmony 900 if you want RF and IR in a consumer-level product. I'm not sure anyone else is still selling such remotes at the consumer end.

The other alternative is a strictly IR-based remote and a repeater system. There are a few type to choose from:

IR-to-RF to RF-to-IR repeater. A base station receives IR and sends RF to another station that receives RF and sends IR. This is a wireless link.

EMI to RF to IR. This is comprised of a special RF transmitter that sits inside your remote in place of one of its batteries. It picks up small electromagnetic interference from the circuit board of your remote when you press buttons and sends that same information over RF to its transceiver which then spits it back out as IR inside a cabinet, behind a wall, etc. This is also a wireless system.

IR to IR repeater. This is a wired system. You have basically a connecting block with a single IR receiver on a wire that you would place somewhere in line of sight of your remote, though concealed enough that it's not a distraction. Then you also have wired IR emitters (they're tiny) that you stick onto the face of the hidden components.

In every such example every component in your system will receive every IR signal every time. There is no routing of specific signals to specific components. If you needed something like this (you don't) then you'd be looking at a pro product (older generation or current) and spending a few hundred minimum. Note that if you go the pro remote route as DIY, that you should only consider a product from URC and make sure the seller is providing you with the required software. Otherwise you're looking at likely a minimum of $1000 to get someone to drop one into your system professionally.

In your situation, I'd recommend a wired repeater from Xantech with as little as 4 output ports. Easy as pie to set up and should cost you no more than $70 (maybe less than $50 if you look around). If you have money to burn and don't want to buy matches, then get a custom installer to come out and set you up. :)
