Preparing for a likely eviciton

[Dante Balassone]

eviction* (caught the typo in the heading after posting)

My wife and I inherited tenants with the property we bought last July outside of Philadelphia (Upper Darby).  One tenant has had continuous issues paying rent and was more than 10 days late this month, which is considered a nonpayment in PA.  We are now opting to terminate the month-to-month lease and require the tenant to vacate by April 1, but the tenant is refusing.  

We will likely have to initiate the eviction process in April so I am seeking an attorney (ideally flat rate for eviction) to process our open-and-shut case.  Any insight on the duration of this process will be be greatly appreciated too!
