OP I'm not what that repair might cost, but others are saying that for the cost, it may be worth it to get a new guitar. If it has sentimental value, it may be worth it - to you - to get it fixed. I've seen worse.
I couldn't help you with a repairman, but a competent luthier should be able to re-glue the neck, then fill the finish cracks and have it looking pretty good. The more cosmetically perfect, the more the repair will cost.
