a small computerized maintenance management system for a small team

We are looking for a internal system to handle our task requests, preventive maintenance scheduling and reporting needs. For this purpose, we require a small computerized maintenance management system that is web-based. There will be 1-20 users. It should include work order tracking, asset management, and the ability to generate standard reports. This system is required for a small team that can effectively accept job requests, allocate them to operators, and report on all received, not completed, and completed jobs. I do need it to be able to import and exported by csv. The system must include site information such as areas, names of tenants as well as job descriptions and the capability of tracking job requests and should have an operator allocation process. I am open to any suggestions as to how the allocation should be handled.
