You should check to see if you can have a large dish, Iceberg is in a similar situation, but he is on the board of something and he is allowed to have the dish on his porch.
If you can't then you will be limited to Ku band(Theres a lot of ku band stuff, so I am not sure if I want to call it a limitation).
You will need a 31" - 39" dish, you are most likely protected by the FCC rules allowing upto a 39" dish.
If you can I would say get a 36" or 39" dish otherwise you may want to upgrade later.
For dishes I like the Fortec Star, Azure Shine, and Geosat brands.
For LNB's I like Lava (no name brand, but works the best), Fortec Star, Others will recommend the Invacom but I have had bad experience with this LNB so I can't recommend it.
A HH (Horizon to horizon) motor like the Stab, SG2100, Geosat are nice motors which will allow you to receive everything or almost everything in view of your location.
For my main setup I use a 1.2 Meter Geosat dish and I can receive all Ku signals, and some of the stronger C-Band signals.
