Looking for Senior PHP/MySQL Developer

We have transitioned to a task based system and the leads system will be built around this. For example, when a leads contract needs to be sent to a customer, a task will be created within the system that will notify the employee that this task needs to be accomplished. The task system has already been created by our existing developer. Now the interface for the leads system will need to be created as well. Existing code will need to be used from the existing module to lessen the workload for the transition.
