appealing pending PA license suspension for simple possession in south carolina

Stopped 3/13 in south carolina and ticketed $700 for simple poss of marijuana. the fine was paid cash the same day, being lead to the magistrate by the ticketing officer in order to pay. my license is now pending suspension 7/13 in PA due to this ticket. is there any possibility that i could win an appeal of the suspension, or "plead down" (i realise this is the wrong term) to a lesser length suspension? OLL is likely not going to be accepted for me, since there is a bus stop at the bottom of my street, however i can prove that since i do contract networking and IT work that most job offers for me are well outside of any local bus. secondary, if i appeal what exactly can you do for me that i either cannot do myself, or will be 'too difficult' for me to do if representing myself?
