Wow. I have to say that you have a serious problem Bert. You dont want to do anything for yourself. Sounds like you may be spoiled IRL. I have been modding video games for years and I decided to come back to my roots with a pokemon hack, a lot this stuff is simply nitty gritty coding, hex editing and that stuff. I am a total newb to this scene but, I was hacking xcom back in the day with notepad paint and a hexeditor.
I have been doing kotor and fable stuff recently with a small detour into GTA: SA. Sadly I would have to say I see people that want there work done for them in all these places. I like your idea, it just needs some work. The starters however are terrible and Mew shouldn't evolve into mewtwo thats a terrible idea. Mew and Mewtwo server two different purposes. Mewtwo was a pretty versatile sweeper back in the day while mew is a general purpose pokemon that could learn any HM or TM .
And having a three legendaries in the evolving line of your starters is terrible.
The suggested trio is a fine starting set though I prefer my starter to have two evolutions to my starters. Slopoke, Hondour, and Shroomish are all decent pokemon for pve play.
I think if your going the richboy route you Don't have a pokedex quest, and you make the starters the Rare pokemon that NPCs have.
Growlithe, Pikachu, Snubull, Magmar, Jinx, Electabuzz, Marill, Phanphy, Skarmory just to name a few. Try and look at what the Pokefanatics, Richkids, and Cooltrainers have and go from there.
