Okay so I was going through yet another playthrough and didnt want to spend so much time on getting the levels and gear. So I created this file to get the following levels and gear to make your assassin awesome.

100 Alchemy
100 Archery
100 Enchanting
100 Light Armor
100 Lockpicking
100 Pickpocketing
100 Smithing
100 Sneak
100 Speechcraft

Note: This will make your character level 56. 

Gear:

1 Ebony Bow
500 Daedric Arrows
1 Mil Gold
1 Full Set Shrouded Armor*
1 Valdr's Lucky Dagger
1 Skeleton Key
 
 * (I recommend this mod to change the looks of Shrouded Armor to look more like an assassin. http://www.nexusmods.com/skyrim/mods/4632/? )

There is much more added to this batch file including all perks for the skills upgraded. Leave a comment for criticism good or bad. And any suggestions to make things better would be cool too. Type  (bat assassin) in the console to open the file ingame.

Note: Newest version has pickpocketing fixed for your character level will be 59 or 60. Sorry for inconvience for anyone who had issues with that.
