[RM2K3] COMMERCIAL GAME HELP

I've got a new game in the works and I'm creating it on the legit Rpg Maker 2003. I'm thinking of doing it for commercial, and I want to:

(1) Know where I can submit my game and have a realistic chance of profit (versus making pennies per dollar, or having them take all my money and not report when the game actually sold)

(2) I want to know what is and isn't okay in terms of that for visual and audio (mark in red or something). Keep in mind if enough stuff is, I'll consider it a dealbreaker anyway and simply have the game free:

• RTP images
• RTP songs
• online visual (jpg or png) or audio works (MP3) if I got the author's permission
• online visual where I didn't manage to locate the original creator, but credited where I found it and who posted it
• Stuff that I drew or recorded myself
• A photograph
• A photograph of a painting, usually which either I painted by number, or which someone locally painted and gave us (this would include paintings by my grandpa)
• A MIDI instrumental version of a song (that is, an instrumental cover)

Nvm. I don't wanna do it. Kindly delete this thread.
