execute c# unit test cases without visual studio and executing them in intervals

I have developed unit test cases in c# using visual studio 2010 ultimate SP1, i have a requirement such that , i need to execute them without VS2010 and need to control the order and time of execution, Is there any scheduler which fulfill the said requirement.For eg : i need to execute for eg: TestCase1 for every 5 min, Testcase2 for every 10 min etc...The intention is to check load on server and performance evaluation.Unit test cases are developed for WCF operations.

Thanks in advance.
