Remember, this is your business at hand and you want to promote so that at least you get some benefit from it and move it to the next level.

Here below is a list of things you could do to confirm that you are in the right track before you can outsource projects:
Is it an agency for real?
The demand for the services of the agency has actually gone up. Freelancers also hope that they can get a job to keep them going. So, some of them have instead chosen to assume the image of the institution so that they can win the projects, but they are not delivering.
What is the mission of the agency?
The agency's mission statement will help you see what they have to offer you. You need to check what they say and what they promise. It should be clear that they have a mission to provide the best services that you need and at the best cost.
