Bugs on a joomla websites... (second try)

I have few bugs to repair on a joomla website. The website is located at [login to view URL] A) First, joom comments doesn't work. It's installed, but when we want to post a comment, it doesn't put it on the website. No idea why. The administrator can not even see the comment. B) Joomfish. On the website, there are French, Thai and English. For a reason with don't understand, joomfish doesn't put the 'URL' for the words 'restaurants' Bars' and 'hotels'. All the other words work in the url, but these doesn't appear. So, the button for the translation do not work like they should do and it gives a 404 error. We want ALL pages to be fine with good URL when clicking on the language. This website has been changed many time and we believe the configuration, install + uninstall other components, made few problems. If we pick someone, this person will be paid ONLY when it works perfectly for these 2 things. It might no be big things, but if you bid too low and can't finish the job, you won't be paid and it's not our problem if you bid too low. We want to get these things done so better bid a little higher and be sure to complete these tasks. You must do the work quickly. Let's say 2 days. And I tell you that someone already tried and failed. PS: You can NOT change joomcomments or other components. If there is a conflict, maybe we can uninstall a component or something but the idea is NOT to modify the website and correct these 2 bugs.
