Do you have anything to offer a prospective programmer for your bank (money, MV creation, UST/VSQX creation, MMD creation, instrumental creation, art, etc.)? Failing that, have you looked at any and all available tutorials your search engine of choice could find? A full 3 pitches is a lot of work, even with a premade base. Even the more philanthropic parts of the community would at best just offer to do a single pitch and you'd have to copy-paste the oto and work from there on your own. It's unlikely that you'll get all 3 pitches done for nothing in return.
