Where do we start?
I think we need a little more info.
1. What configuration -- 5,6, or 7.1?
2. Are the “rear-speakers pre-wired to install in-ceiling speakers” for rear surround in 7.1 or side surrounds in 5.1? If 5.1, then the 2 rear channels of most 7 channel receivers can be used for your second zone (outside), as long as the receiver is capable. Otherwise you will need separate amplification.
3. Front right/left speakers – Floorstanding or bookshelf (sounds like bookshelf)? Size limitations?
4. What are your point of purchase options? On-line, consumer retail, specialty retail etc.
You can definitely separate speaker and receiver manufacturers. The home theater speakers should be of the same brand and preferably the same line especially the front three, but the surrounds are not as critical of this aspect. In this budget range I would try and stay with 8 ohm speakers.
There may be an issue with an in-ceiling speakers used outside due to weather conditions ie. extreme hot and cold, humidity or lack of. I know some manufacturers make them but I don’t know which. My preference would be to use the same type outside product.
OK! Making some assumptions this would be my preliminary recommendation for a 5.1 system.

I would also suggest impedance matching volume controls for the outside off zone 2.
This is a fairly tight budget, but not impossible.
I hope this helps.
