You will need a decent view of the southeastern sky, since the satellite is at 25.9* elevation from your location. However, unless you live in a highly wooded area, this should not to be too hard to do.
As for dish size, I would recommend at least 7.5-8', and a proper international circular feedhorn, like the ADL CP-300 or CP-400. Because it is an Atlantic satellite, spaced 3* from nearby satellites, many have been able to receive it with a smaller dish and the more typical linear feed with a dielectric insert put in; you might not get all the transponders reliably this way. However, if you want to use such a feed arrangement you may get good reliability with a bigger dish, e.g. 10' or 12'.
