I've got a few from Gemini Vapors (Octo and Adam & Eve), both are 15ml, 0mg. I've also got a bottle each of The Toucan & Yabba Dabba from Smoky Vapors, both are 15ml, 0mg. I don't think I've vaped more than a mil or so out of any bottle, so if you'd be interested in any combo equal to your 30ml Looper, let me know.
