Its a straight forward job to do so any mechainic should be able to sort it out, you could try to check the bolts yourself just incase there loose, but be gentle, the are a small bolt and only a bit over pinch tight.
You can order the gasket set from your chassis number, get them all, the 2 seals for around plug holes, bolt seals, and cover seals, probably be around 30 euro total for parts
