Greetings
HiF 
There are definitely some Green skinned players hanging around, so I'm sure you'll be able to ask for their advice on how to win with them Orks.
If you're wanting to sell your stuff, why not post up what you have in the
Trading board? I've tried selling stuff through eBay in the past, and its honestly not worth the insertion fees. Better to find people directly and organise it privately.
Before I lose your attention, make sure you have a quick read through of our
Forum Rules. I'm sure you're a perfectly reasonable Wargamer & Person, but if this is your first forum, then it can't hurt to familiarize yourself with the rules

I'm a hobbyist artist myself. Do you have a DA account or similar you could link?
Hope you enjoy your stay here. ^_^
