I recently had the alternator replaced and was informed that the front engine seal has a leak in it. How extensive is this to repair and approximately how much money am I looking at?

Can you be more specific as to which front engine seal? Crankshaft or Camshaft? Are they recommending replacing both? These should be replaced along with a timing belt replacement, how long has it been since the timing belt was replaced?
The timing belt should be replaced every 60,000 miles. If the belt was to break, engine damage will occur, so if there is any question, it's a good idea to replace the timing belt and all the front seals at the same time.
A shop will charge around 3 hours to replace the front crank seal, but I bet your friend is capable of performing this job.
The approx. 3 hours is for the crank seal, but the timing belt is removed during this repair, so no extra labor, just parts.
I had a friend fix the alternator, who works on cars often, and he believes it is the main crankshaft seal in the front. I have not owned the car very long, came to me with these problems, so I do not know when the timing belt was last replaced.
He could, but I gather its a pretty extensive job, and for that he doesn't have the actual time or the tools necessary. How many more hours labor for the timing belt?
hope your seal dosent blow out like all the ones ive tried.if leak persists and u find problem please let me
