Please modders help me out.

Add Guards + Monster to the map (from skyrim itself, just pick one and add it to the map)
Add an item to the map (I already found a mod of the map)
Add a quest system (Just have a system that player can follow)
Add a simple dialog (for quest as well) (just simple text box)
Add cinematic (I have a video you just need to convert it to skyrim file)

I'll fill in more details if you are interested. This is just an overview.
If you are pro in scripting this job is easy.

Easy job please help me out. TY

I just don't have time as I'm a working student and basically only have 6hours of sleep/eat/freetime/study

This is the map http://skyrim.nexusmods.com/mods/25003 (frosty keep) A very simple map, at the bottom of it I want to have a chest that will have a sword and armor http://skyrim.nexusmods.com/mods/6348. Outside/inside entrance of the dungeon will have soldiers and just randomly fill the dungeon with monsters (few at the start and more closer to the chest).. after the player picks the sword a dialogue will occur (sword talking to the player) "Kill them...kill them all..." then the player will kill the guards on the entrance outside of the dungeon. Basically the player will start outside of the dungeon and he can pick up a quest from one of the guards.

1. adding guards isnt just that easy, there is data packages, patrol ect you have to set up, can't just copy them around, you still have to work in the linkref systems to make it work.
2. the map, asuming its a mapmarker, requires a location, and markers for that, simple enough. the beth tutorial covers that.
3. a quest system, well building a uest do take time, since you work in AI packages again, asumeing its via npc's. if not then via scripts, you still have to build the quests, and sort the scripts to call the right things, and cover all bases so nothing fails, when the players aproach it from a diferent angle then intended.
4. dialog implies voces, so you need voice actors for that, and before that, you need a basic idea of the quests. Further you need the dialog written before you can record it.
5. convering can be done as stated in one of your other threads, but can really be a hazzle.

All in all, there is about a good week of work in this request, even if you are king of the scripts.

My advise would be to check out the official http://www.creationkit.com/Category:Tutorials and try and se how much you can make on your own and then come here, with questions for help, with what ever problem you might have. We are normally quite helpful and like to give out of our ideas and knowledge.
