After Awarding the Project
Once you have awarded a project the contractor is been notified about your project award. He can further review your terms and milestones and will further accept or reject the project award. You will be notified in each action of the contractor.
Altenately you can unaward the project to that contractor or remind for project award.
When the contractor accepts the project award then a common workroom will be created between the two of you where you can communicate with respect of your project. You can create milestones for your contractor, send messages, files ,manage project etc from your workroom.
You can keep an eye on the progress of your project from the workroom.
