塞尔维亚采购需求：营业执照办理、小企业营业执照申请、电子商务注册、营业执照类型、营业执照、上海合资企业

I'm planning to establish a business in Hainan, and I would appreciate your guidance on the necessary steps and requirements for this process. As a Serbian citizen, I'm particularly interested in any specific regulations or documents needed for foreign investors. It would be helpful to know about the registration process, any investment limitations, legal obligations, and potential incentives offered by the local government. Additionally, any insights into the local market, relevant industry trends, and recommendations for reliable local partners or resources would be greatly valued. Understanding the logistics involved in setting up operations, including permits and compliance issues, would also be beneficial. Looking forward to your detailed advice on making this venture successful!
