Don't be too discouraged. Scanlations are produced because there's no other source for a translated version. When a commercial translator announces that they purchased the rights to a manga, scanlations usually stop. Unless it's a very popular series like Naruto, where you have a large number of people who can't wait for the translated volumes. There is a market for non-digital translated manga.

I would like to buy funny, high quality doujin(dozin?). A few volumes of Comic Party anthology comics were translated years ago, and I was sad when I learned how many volumes were left untranslated.

Tankouban(tankobon?) manga volumes sell for $10-14 US dollars in North America, so I guess I would expect a price in that range. I don't know about other formats. Do you mean you would translate individual comics or collected volumes?
