I already own a paid style, however the person who created the style no longer works for the company who still owns and sells it. I have permission from the owner who stated I can upgrade it if I can find someone who is able to do so for me. (Proof of our chat can be provided if requested.)
The style was originally created for XenForo 1.1.2 so it is a bit outdated but when installed still shows decently well, but since the templates are very outdated it just needs to get an update.
If this sounds like something you can do and/or would be interested in, send me a personal message with any questions you may have and your cost if any.
