After the owners' committee is established, can I still recruit a preliminary property company in the name of a developer?

No.

There will inevitably be a gap period between the completion of the community and the owner's move-in. In order to ensure the normal operation of the community's greening, environment and various facilities after the owner moves in, the developer will hire a preliminary property service provider. The company serves the community.

The early stage property service company is a property company hired by the developer, but this does not conflict with the owner's choice of property company, because the early stage property service company, just like its name, only serves the early stage of the community. After the owner signs a "Property Service Contract" with the selected new property company, the preliminary property service company will also withdraw from the community.
