Hi Reaver, welcome to the boards.
Rather than just posting here which is used more by players than the industry, can I suggest that you get in touch directly with the big manufacturers of paint & equipment. Make sure you have a full business plan & details of what you are hoping to do & what kind of help & sponsorship you are after before you start to call them though.
Good luck in your venture, nice to see paintball spreading across the less recognised parts of Europe
