Sand blasting and new items (Southborough)

Hi all i work at aspens charity pembury and the woodwork studio/session have some metal pieces that are rusty and need sand blasting. Is there anyone on here who would be kind enough to sand blast them for us for free or do us a really good deal on them.
One metal box and lid and a metal frame


We are also after more metal items we can upcyle and make into quirky new furniture
