Online Portal for Leasing and work orders?

[Tim Flanders]

Hi,  I'm trying to find a software company that can build a online portal into our website?  In this portal we would like to be able to send automated emails as reminders for rent payments, allow tenants to view their documents (lease agreements, or payment history), pay their rent online, and allow tenants to create work orders from online.  It would be ideal if this worked hand and hand with rent manager as we currently use this software.  Does any one have any recommendation?
