[MALAYSIA] Desk Research on "Building/Construction Materials Suppliers" List

I am looking for several assistants to help search about green building material suppliers list in Malaysia. However, the green building concept is still new in Malaysia and I can accept just general suppliers for construction and building materials. My target is to get at least 90 potential suppliers' names and websites only for my report. If you're interested, below is the requirement:
1. Propose to me a milestone offer and the target that you would like to achieve.
2. I would wish to know if there is any green materials suppliers for construction.
3. I am looking for suppliers/distributors. I am not looking for B2C companies like IKEA or Home Pro.
4. If possible, I am looking forward to a list that consists of general product suppliers rather than a specific product's supplier.

Note
1. Once confirmed, I will give send you a Google Sheet and you can list down the names you found.
2. I had to go through the Malaysian Institute of Architects(PAM), Malaysia Green Building Council (BCG), Construction Research Institute of Malaysia (CREAM) and Building Materials Distributors Association Of Malaysia for my pre-understanding.
3. I am hoping to see the names that are not found on the Building Materials Distributors Association Of Malaysia's website.

Thank you.
