To start with I'm only after single room AV control, no lighting or a/c etc - only a few AV components with a PMC3 + PLX3.
I've been using composer so far and then making customizations in SB.

I haven't had any training in SIMPL yet (on a waitlist) but would be happy to pay someone to start from scratch in SIMPL\SB (whatever they prefer) after discussing the customizations I'm wanting which I don't think are straight forward in SB.
I so far have basic things like button mapping and page flips how I'd like - but using the 12v trigger and conditional functions is beyond me at this stage.

I'm guessing programming from scratch in SIMPL might be more than a few hours work - but that's fine if it will do what I'm wanting.
