My main area of interest has always been zoas and that's treated me pretty well. I keep all kinds of corals in my mixed reef and I'm lucky to have built a good part of my overall collection via trade with shops and other hobbyists. Through r2r and Instagram I've met other collectors all over the country and regularly swap via shipping. With my larger colonies I also regularly work with local shops. I either get cash (they need enough margin to do a 3x mark up) or we'll swap coral. I usually put my high ends up here, on IG or rarely on FB (mostly when some tags me... FB is a wasteland).
As for the second part of the question I always tell people the same thing: 'it's not as easy as it looks or as fun as it sounds.' Fact is I've lost plenty of sleep because I have to stay up late dipping something multiple times within a week. Or, there's that time my 20p colony of A$skraks melted and I couldn't do anything to save it. Amazon has me tagged for frag plugs, furan-2 and lugol's at least twice a month. The point I'm driving at is that there's a number of expenses around propagating stuff, even when you're doing it at a small scale. Don't get me started on adding strains to a collection. Especially with zoas people often want the 'latest and greatest.' The real reality of the matter is that if you bat .650 with zoas surviving and growing out into a colony you're an A++ hall of famer. All that being said, the goal for each and every reef keeper is to grow that frag or mini colony out into a nice big healthy colony that necessitates fragging. In short, there's no 'easy way' to sell stuff short of passing it back to your lfs, craigslist, or fb.
