XENFORO 1 => 2 - Port an existing Addon from XF1 to XF2

There is an Xenforo add-on with 31 files and 132kb code (192kb on disk). The offered job is to port this add-on for XF1 to XF2. No concept, no discussion, no decisions - just port file by file to the new syntax of Xenforo2. Please make me an offer for a final version, done in the next days. Please start your answer with the line "Xenforo Port". I need someone experienced in Xenforo, wo knows the differences between XF1 and XF2. The add-on should be "translated" in one go without searching how to do these or that.
