Slight PERL modification

The application has already been written and it works very well (its a commercial application) the application can be downloaded so that it can be trialed for a period of 30 days. I'm not worried about the trial period (Its more than enough for me to see if it works properly), the only problem is that my customers would keep getting an annoying window that tells them that the license will expire in 29 days or so, hence I can't try it properly. It is this window that I would like to get rid off and I don't think it be a very difficult task considering that the code is all there. Another modification that I would like to get done (its a web mail application) is when you first want to sign up for a domain name it gives you a choice of all the domains that the server is managing, I would only like to choose one domain that is visible to the public and the rest I'd like to manage in-house. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased.
