First, projects belonging to the centralized procurement catalogue are generally purchased by local centralized procurement institutions (equivalent to centralized agencies, usually institutions). For the specific transaction process, it is necessary to consult local centralized purchasing institutions and public resource trading platforms.
Second, the projects that social bidding agencies are allowed to act as agents (projects outside the centralized procurement catalogue, under the procurement quota, or projects specially licensed by the regulatory authorities) are selected by the purchaser according to relevant laws and regulations, and online operation is not required, so you can directly find a familiar bidding agency. If you are not familiar with it, you can consult the local government procurement supervision department.
Just look online, first, I don't know his specific strength, and second, he may not have business contacts in your local area. Now there is another development trend. The intermediary services provided by government procurement in official website may be listed in your local government procurement bidding agency list. Every place is different. You have to consult the local government procurement supervision department or website customer service for specific operation.
