What is your problem? You've come onto this forum saying that you've done a few corporates, shorts and weddings. Then you ask for very basic advice on editing a music video. Three people experienced in the field you want to enter have given you advice but just because it's not the step-by-step guide that you were expecting, you throw a hissy-fit.
and do you actually read the answers you're given? I can't find anywhere a comment that "‘It doesn't matter if your effort isn't up to par". I can't find any suggestion that enthusiasm and inspiration are your downfall. In short you're quoting rubbish.

If you're 25, three years degree and have run a production company for 6 years you started uni at 16 then? Oh no, you were running a production company as a student. Big deal, we all did that mate. I suspect that you did a media studies course as opposed to a proper film school, otherwise you wouldn't have this negative attitude to experienced film and videomakers.

Read what Turnmedia, Mark W and I have actually written. All of it is relevant to what you want to do. We get dozens of semi-pros asking for us to sort out their productions (without payment) and we give advice which you could do well to heed. I suggest you actually read my last post, as opposed to throwing your toys out of the pram just because it wasn't what you expected.

Edit: Proper Production Companies also constantly take on jobs which they can't do themselves. They then sub-contract it to someone who can. This is something you should consider, rather than expecting a crash-course in music editing from this forum.
