Soo.... do commissions?
Been lurking since before you re-appeared, but got a collection of a smattering of models that I wanted to just get painted and stay shelf queens since I havn't played in a decade.
Though still also searching trying to decide on chapter/paint themes, since it doesn't have to be unified as it's not a playable army.
Unfortunately this is more complicated than some other side gigs, and it's an interesting issue broadly as 40k becomes more popular. I ran the numbers on this a few years ago because I sometimes get asked. To be clear I don't consider myself competition level painter and really don't "enjoy" single model endless hours stuff, but I am decent at cohesive army painting and have spent a lot of my time developing ways to do better things at a faster pace.
The reality is, time and materials vs what I'm willing to charge for the range of quality I feel I can commit to just never quite matches up in my head. Even if I were happy with say $10/hr, I think my DW army would have been say 60-70 hours all in for 46 models. So by time you factor supplies, figure $800 (including test paint scheme work but not including kits, or building and conversion work). Obviously if I decide to value my time at even $20 an hour, then that gets even more ridiculous. Then if you consider a "risk" factor (person isn't happy, shipping damage, person charges back via PayPal, model it has a broken part and it was bought on eBay so GW won't replace so there's an argument about it, etc.), you need some room in all this. Then there's taxes that maybe enter the picture depending (good and bad because hobby income).
So all in, is someone willing to pay 2 grand for me to paint their small model count infantry only army? Maybe 3k if it's got tanks or like 4k+ if its stupid swarm shit with eyeballs like guard?
For example I had someone look at my marine army below ask if I'd build and paint say a tank for them for like $50 which they felt was fair, when honestly just building and paint prep is maybe 3-4 hours to get it all done (sanding gap fill magnetization etc.) and primed. So expectations tend to be orders of magnitude different from reality. That makes sense in the context of people who don't know how it all works not thinking hourly, but just WAG "personal value". That gap between perceived value and actual work effort needed is often huge in my experience, and also probably why there's seas of grey plastic out there.
Anyway that's my story. Also I'm shit at photography.
