I do hope this is going to be a ground mounted dish, as you want a 2M plus, probably the best would be a Channel Master 2.4M, but it will probably be expensive.
In most of the UK we are allowed upto a 1 Metre dish, without needing to apply for planning permission, so I hope you can hide it from view, or have understanding neighbours
You might want to consider a Channel Master 1.8M dish, as a compromise, this should pick up most things.
Setting it up is the same as smaller dishes, you just require a bigger actuator, to get the full satellite arc, probably a V-Box II, to interpret the Diseqc 1.2 commands, then manually drive the motor and store the satellite positions.
Have a search through the members pictures section, for Channel Master 1.8M dishes:
