AWS IAM Policy to allow full access to services, but only on the instances this user created

I would like to write a policy for a new IAM user so that he can have a full access to AWS Services such as EC2, RDS, Cloud Front, S3, etc. However he should be only able to view (describe) and manage the instances/services that he launches. He can't see other existing/future instances/services created by other users. This case happens in a company that wants to outsource some projects to an outsourced company. So the new IAM user is for giving access to the outsourced company to setup the staging & production environments in AWS that belongs to the company. How can I achieve this? Thanks.

Best Regards,

Mark
