IT Helpdesk support

I am seeking a IT Helpdesk Support professional or team to provide technical assistance to our clients via phone, email, and chat at a very reasonable rate. I currently have a very small MSP technology company with about 15 calls a week that need remote support. I have talked with many white label companies offering this service but just doesn’t fit my model of business and the price is more than my clients currently pay. This job would be good for someone that already is serving other clients and can add my small about of jobs per week on. Must speak very good English.
My ideal Helpdesk Support professional/team would charge on a per ticket pricing not per hour unless it was a low per hour rate for the support. I am also open to ideas as well.
