Dome camera body/case

We are developing custom security camera. We are looking for ready off-the shelf Dome camera body/case (just mechanical parts and optical dome cover). The freelancer has to execute market search to find camera body/case manufacturers, who can manufacture Dome camera cases in mass production. We will provide freelancer with search criteria, such as target sizes (4-8" diameter, 2" height of body), hardness (indoor-outdoor, IP??), mounting options (ceiling, wall etc.) and target price (3-20$). These details will be more accurate on project start. The freelancer will have to contact manufacturers, receive catalogs, mechanical drawing and estimated prices. The project result in report with many manufacturers (more than 20 at least). We might consider bonus payment for outstanding results. The project will be approved only after we successfully verify information with the manufacturers. Preferable freelancers from China or Korea.
