Hi!
I saw your job offer, and I think I could be interested if you don't have a deadline too close.
You can see how I work on this page: Spine: Twitch
You'll also notice I already know how to set up skins for an isometric character.
I don't usually take freelance jobs, but when they look challenging like yours (or are extremely cute) I make an exception.
My strong points are rig setups, my rates for rigging are 45$/h
For reviewing your pipeline and training someone to do it 75$/h
Setting the rig will probably be the longest part of the process, but if you do it well, adding new skins or animations later, perhaps for future updates of your game, should be much easier.
I work best when I have a complete PSD properly structured as a starting point, but we can also discuss how to best prepare it.
My latest freelance project has been implementing meshes and 2.5D effects in the HighRise app: http://www.joinhighrise.com/ https://apps.apple.com/us/app/highrise-virtual-world/id924589795
For example, here's a brief gif testing 2.5D head turns allowing their assets (1000+ in game) to seamlessly work with it:
In case you didn't find them, here's a couple gifs of turns and isometric views I did:
I'm of course also up to date on all the new Spine features such as skin bones.
Please let me know if you're interested!
Cheers,
Erika
