create a conceptual model from the following summary - using Chens notation or crow's feet notation.

Suppose you own a small warehouse that you are converting to a set of workspaces for small, startup companies. You charge a small rent for each company where the amount of the rent charged depends on the size of the company and the number of employees. You will need to keep track of general information about a company, such as its name, owner(s), and contact person. Since most of the companies are startups, you will offer a service that will keep track of the projects that the companies are working on. This will be done to facilitate interaction among the companies, should they want to share resources. Each project will be assigned a project number. You need to keep track of the date the project started and ended, as well as a description of the project. You will also need to keep track of what skills are needed for the projects and who possesses those skills.
