configure MediaWiki

We are about to setup a MediaWiki on our server . Four tasks are to be carried out: 1. enabling the upload of pictures into the wiki 2. fitting in a simple customized logo made of nothing else but the following 10 letters ('ab' might be modified when before you start your work): ? ? ? ? ? ? ? ? ? [[abwiki]] 3. adding the smilies extension ? ? ? ? ? ? ? ? ? [login to view URL]:Emoticons 4. setting up some backup facility like ? ? ? ? ? ? ? ? ? [login to view URL]:Backup - [login to view URL]:Backup_%26_Restore - /usr/bin/nice -n 19 /usr/bin/mysqldump -u $USER --password=$PASSWORD$DATABASE -c | /usr/bin/nice -n 19 /bin/gzip -9 › ~/backup/wiki-$DATABASE-$(date '+%Y%m%d').[login to view URL] The backup facility is intended to transfer the entire data to a different server / local PC + restore (some domain or different one). Please mention in your offer? briefly, how you will set-up the backup. You see, no big deal at all. What do you think the whole job is going to cost?
