From my readme:

Author: Manargo
Date: March 7, 2007
Version: .8 (pre-release BETA)
Mod/Plugin: delivery_job.esp

Purpose: This mod allows the player to do delivery jobs for the new Gold Horse Delivery Service. In every major city you can find 7-9 jobs (randomly selected each time) that you can deliver locally (that's over 60 jobs locally). After an advancement in the courier business you can deliver inter-city packages from branch to branch for more money, and then finally after that you can deliver supplies to some of the inns in Tamriel.

You are penalized for fast traveling for inter-city packages only. Even then, you still get a substantial reward for doing them. (100 for doing them, 50 for fast-traveling)

Possible conficts: Since I have added a branch to each city, obviously it might conflict with another mod who puts something in the same place. I edited landscape in two cells, so that might also throw conflicts. Other than that, I can't think of any other showstoppers. When in doubt, change your load order.

Installation: Unpack the compressed .zip file to your C:\Program Files\Bethesda Softworks\Oblivion\Data folder.
You should be copying over the .esp, some textures, meshes, and some sound files (blank .mp3s made courtesy of the TES4 Plugin Utility).

To uninstall just delete the .esp and the following folders:

\data\meshes\delivery_job(meshes)
\data\textures\delivery_job (textures)
\data\menus\icons\GoldHorseCourier(icons)
\data\Sound\Voice\delivery_job.esp(blank mp3s)

Thanks for the download and I hope you enjoy it! This could be the full version, but I might add more stuff in the future (along with taking care of any bugs).

Notes: I should have a WIPz thread up on the official forums. Please stop by and leave some feedback and suggestions.
