Looking for Thoughts on Content Creation from a DM's Perspective

Hey there, let me provide a little context for this question. I'm a several year veteran of D&D (3.5 specifically) and have a competent or higher understanding of the game, mechanics, numbers etc etc. Recently a few of my friends, who are all complete tabletop beginners, decided they wanted to try out the game. Now, I had an idea for a campaign setting that they were really interested in so I took on the task of becoming the content creator (basing everything off 3.5 but with a respectable amount of homebrew). I have gone through and written up a series of classes, races, items, new mechanics for certain campaign related flavor, story and whatnot for the world etc. Basically all sorts of neat stuff the DM would normally create or use over the progress of the game. However, while doing this I started to remember that I have no DMing experience or knowledge myself and am fairly certain I would be quite bad at it regardless of my mechanical knowledge. My main question is this: As a DM would you be willing to use someone else's content for a game or would you much prefer creating everything on your own? Is it considered rude or a faux pas to delegate content to a DM and basically say "you must work within these rules" even if the "rules" are just a particular flavor setting and any calls or rulings are still at the DM's discretion? My idea is I want to work together with a DM who has experience with the game in order to create a relatively well balanced but detailed setting with a lot of unique content for these completely new players to enjoy. After the creation process however, I would fade back into the role of being just another player as that's what I'm more comfortable with. Plus, I just like the idea of an experienced DM helping completely new players learn how to enjoy the game in more of a casual setting that isn't as unforgiving or strict on the rules as a min/maxing group may be. So, any DMs out there that read this, let me know what your opinion on this situation is. Do you think I should just man up and give DMing a try since it's content that I created? Or would you enjoy the idea of working with someone else who is decently knowledgeable to create something awesome for beginners? I appreciate any feedback you could give, and if you happen to be interested in more details I can drop some of the content/whatever else in here for you to look at. Thanks for reading, sorry for the long-winded post. :)

If you think about it, you're basically describing exactly what many DMs do all the time with a prepackaged setting like Forgotten Realms or Dragonlance. My personal opinion is that you could find someone willing to DM that setting for you, but if the players are friends of yours, I'd try to convince you to give DMing a try. DMing is very rewarding, and you're already doing all the hard stuff. =D Give it a shot!

Second what Aaron says. If you've put that much work into the world, then you know it intimately. Give it a go. You'll likely enjoy it. Also - pathfinder has gobs of premade adventures called Adventure Paths and Modules. Just like what you describe - everything is done for the GM. GM just has to read the material to be ready to play.

It's absolutely fine to create stuff for someone else to run - big publishers do it all the time! I know some people though who enjoy the quiet, steady approach to inventing a world but hate the sometimes-frantic pace of GMing a game, so if that's not your thing don't feel pressured. However, as Aaron says, it's a really rewarding role, so you might find that it's worth trying it yourself among friends. You might discover you love it! Good luck!

Thanks for the replies! I guess I could always do a few test sessions as the DM and see how it goes and then work from there. One of the secondary reasons why I was looking at getting someone else to DM the setting is because it would get another set of eyes on it in order to help polish it up a bit instead of being a closed project.
