I'll leave you a couple notes based on the experience we have had preparing our business this year with my teammate :
1- build a small game first. On average, the revenue from the first 3 games of a given team makes less than 300$ on mobile stores.
2- planning to release your game on pc ? It has clearly not been designed for mobiles anyway (the gameplay and controls are too complex). But just note that there is practically no html5 market on desktop, and that the pc/mac/linux world requires a higher quality standard than mobile.
3- You should try the publishers route, but only accept a fair deal (small upfront payment plus 50 to 70 % of royalties for example). They can get you front page features and they'll get your games validated fast on the stores. Last but not least, they generally have a network and cross-game promotion which is absolutely required when starting on mobile phones
As for the selling model, most of them seem to ask for freemium (free game with ads, plus In app puchases to unlock more content or so).
4- But start with a small game (unless you have a strong source of revenue maybe). It can feel heartbreaking to work for 3-6 months on some project and only get a handful of bucks in return.
