c# Youtube Project 2 hours Work

Have a software that can create videos and have added 90% of code in order to upload videos, but need to add the oauth part to get the id/secret that will allow upload for more than one account. Should be 1 or 2 hours work max if you know what you are doing. Currently the software can manually login to YT and retrieve channels (this is to allow future features for Live Streaming). I understand there is a method to allow uploading to channels using API3 I have a url for StackOverflow that shows this. Code is there to read the JS file with ID/Secret to allow upload. But I need to know how to 1, get the ID/Secret for more than one account and store, so user can select in drop down the account he wants to publish to and it then retrieve these from dbase to publish. Like it done today on TeamViewer if possible. Don't bid if you can't do today. Don't bid crazy amounts for a couple of hours work.
