254265 CSS / js repair

Our site integrates Joomla 1.0.15 and vBulletin. The fancy-ass bloated drop down navigation works great in its native Joomla, but isn't working right in VB, where we kind of shoehorned it in. In VB, when the menu drops, it is be obscured various VB elements. (see attached image) As you'll see in the image, it looks like a layering issue that only effects Internet Explorer 6 or 7 on XP. So, you'll need to have an IE/XP setup where you can test this. Unfortunately, I do not. You'll have complete access to our server and vb backend, both the working Joomla code and broken vb code. However, the site is live so requires caution. Thanks! Let me know if it's a bigger job than I think it is. Payment via SL escrow, released upon proof of working code. Bonus for quick completion. Thanks for considering this!
