autoblogged to be hacked to include keyword into slug

Am using the autoblogged plugin to fetch feeds from Google Blog search based on keywords entered by me periodically . I needed an hack to the autoblogge version which am using so that i can have the keyword for which the post was generated to be included into the wordpress slug. e.g if am processing a feed for "the springs costa rica" then the feed slug should be "the-springs-costa-rica-xxxxx". Where xxxx is a random number ensure that we dnt have a clash if the same keyword has been processed again. Am attaching my version of autoblogged so that the changes can be made as per this code. I need this to be done quickly. Simple task willing to pay $20 for this.
