Assistance with MODx upgrade

I'm a developer myself, and our website runs MODx. I need to do a point-upgrade of MODx, which explicably is failing for me, and I need someone to assist me in the getting the upgrade to work. The MODx site is not complex and uses essentially no modules, but all security recommendations have been followed, and it might be an issue with not catching all non-standard paths. But in any case, I want to hire someone for an hour of assistance in a shared desktop session -- I cannot hand out credentials for security reasons. If you're not very experienced in MODx, this is likely not the job for you, as you have to be more experienced than me or it doesn't make sense. Hourly billing. If you're good, you can do this in 10 minutes.
