ive got a 2004 E320 with approximately 59k. there is a major wobble and noise coming from the water pump pulley. is the water pump shot?

i have this week off and would like the part replaced, can anyone near me replace it for me? i can help but dont have the confidence and i lack the skills to do it myself and dont want to go to the dealer. im near Birmingham MI and have a garage.

should i get the timing belt done as well at the same time?
