Replating silver plated objects like trays, vases, flatware, etc.

I work as a jeweler for my family's jewelry store. We have started taking in repair jobs that involve polishing sterling pieces such as trays,vases, flatware, etc....Now we want to offer replating of silver plated objects like those mentioned. We have a 10 amp rectifier that I am wondering if it will be powerful enough for the jobs. I read that you first buff the corroded areas until you can see the copper showing through. Then you plate the object with nickel plating solution using nickel annode. Next you plate the object in silver plating solution using appropriate annode. Can someone better direct me if I need to purchase a higher amp rectifier or what steps to take to offer a sound service to my customers?

Thanks.

You are making me scared! (Just kidding). I take such care in refinishing and re-silvering my customer's lovely things that you have me worried that you will ruin them. Why not send them to a professional? We service many businesses such as yours and the customer never knows the difference. They think you are big heros! And, please do not nickel plate over good old silver--it ruins it.
