First Go

Mods if this is something that is off topic for this area of the forum please move and my apologies in advance for it.
Recently a friend of mine has informed me about routerboard products that might be of use for what I am looking to setup.
Currently what I have envisioned is doing a Wireless mesh covering a 160Acre community. Approximately 100 to 200 clients.

Based on the searching I have done I would likely have the following setup:
Cisco 2811 for fiber backbone
CCR1036 DNS/DHCP/Authentication
Now this is where my lack of knowledge comes to play.
I want to broad cast out the signal in omni-direction I am thinking a 3x SXT G-5HnD pointing out towards the area I want to cover with over lapping spectrums
Was thinking for the client side of things to to have each client running with a OmniTIK U-5HnD or a Groove 5Hn.

What I wan to Accomplish I want to have to where every client to essentially repeat itself thus meaning that I should technically end up with no dead spots within the region. I think.
I want them to essentially just be repeaters And just provide the signal I want the CCR1036 Handing everything else. I would likely also want to make it so any wireless capable device can connect pending login to the network.
I want to preconfigure and restrict accesses to the hardware being placed on the clients site to where all they have to do is mount power on and surf.
My budget is roughly $7,000.00 to $15,000.00CAD/USD and my roll out time is based on the release of the CCR1036
There are not tall buildings in the area and only minor trees not heavy trees. Also would be important to note that if I can get away from having a central broadcast node(3x SXT G-5HnD) and just have every client repeating themselves I would be interested and likely go that route. However I feel having the node in place would likely prevent alot of issues.

Any Thoughts or guidance would be greatly appreciated, I hope I get some info into doing this with these pieces of equipment as I really am enjoying what I am reading and hearing about them.
