Pokemon cobalt- need info on hacking such as steps

this is my first hack, I made a Zelda ROM hack couple of years ago, worked out really well. I have amazing Ideas for this game, just need to learn how to make the game itself, and combine all the parts to get final product. I need some experienced hackers to make a video for me.

the game will feature all elitefour champs and Gyms, all battle facilities(tree, frontierIV, etc)
