you can remove anodising with caustic soda(drain cleaner)..comes in crystal form you add water to it and drop your parts in,doesnt take long.
as for anodising you again can do that yourself,but if you dont feel upto it then get the yellow pages out,lots of companies in there.
i used one a few yrs ago to get some alloy hard anodised,i think it was mansfield anodising the name of the company.
