Germany importer company request: EPDM rainwater filter

Hello sir admin *****.. I worked in *********** Company in Germany. I currently have a freelance assistant collaboration. We buy one of our products from ********* in EPDM. But we are looking for a new company in terms of quality and price that can do the rough demolition of our products in the quality we want. Sorry for my Turkish, I could have explained it much better in German. Am I in the right place for you on this subject?
I think it will be between 500 and 1000 ladets per month in total. This will be the first station in rainwater purification...
