I'm looking to kick off a commercial venture in Lahore, Pakistan, focusing on food-grade PVC pipes. I've heard that these are available locally, and I'm keen to explore this opportunity further. Could you provide me with more details about the specific products you offer? It would also be great to understand the type of equipment you sell related to this business. Additionally, I'm interested in whether you have any training videos or resources available to help me get started. I'm also curious about the possibility of integrating aquaculture into the system by adding fish at the bottom to utilize their waste. Looking forward to your insights on these points!
