Drupal - Restrict View Results by User Profile field

I have a Drupal View meant to show a list of contracts for a given customer. The user profile has a "COMPANY NAME" field. I want to restrict the View results by this field. Example: User Profile with "Company A" has 3 contracts User profile with "Company B" has 6 contracts Database has total of 9 contracts When Company A logs in, they should only be able to see their 3 contracts and when Company B logs in, they should only be able to see their 6 contracts in the View results. See the following URL: [login to view URL] - When the user "PELLA" is logged in, they should only see the results for PELLA WINDOWS. The same is true for PREMIER ELECTRONICS. Currently, the "COMPANY NAME" profile field is a text field where anything can be entered. I know this may be simpler if that field is a pick list of Taxomony terms. I am open to using that method for choosing the company name... the simplest implementation of this is best. Please confirm that you have read these specs completely and understand the work involved. An general explanation of your approach will be necessary prior to bidding with more details after you accept the project so we can understand how to support it in the future.
