Script to convert the displayname and set as new displayname

Hi All,

Need a favor to convert the existing displaynames to right format and then set the displayname for bulk mailboxes.

Current Displayname - "Ranji Rock MBA\DBA\RISK\FIN"

I need a script to convert the above text to "Ranji Rock MbaDbaRiskFin" and set it as displayname. Could someone help me to remove those slashs in the text and adding the first letter in caps??

Never giveup till you get what to want.
