I have not done much stainless welding, but it is not difficult. The pro's use a special gas mix to weld stainless. I don't remember the gas mix but I'm sure you can find it on the web.
I don't know what welding gear you have or are planning on buying but I would start with what you have and go from there. Flux core is pretty forgiving but the welds are not very "pretty". Slag and weld splatter are common. But the penetration is usually very good. MIG with a CO2/Argon mix can make very "pretty" welds and welds tend to be additive - ie the metal piles up and the penetration is less than what you would have with a flux core wire. To make things more confusing, they also make flux core wire that is designed to be used with gas. I've never used that. Don't bother buying the flux core wire that Harbor Freight sells. I have never used it but it has a very bad reputation.
