Perl based forum - custom

We need a simple forum made in Perl. Please don't suggest existing solutions, we have very tight security requirements and need a solution that matches the specs, no more and no less. The entire job description is included in the attached PDF. To open it, please read at the bottom of this. You will need to create a "bitbucket" account (free) and update the project there daily so that we can see the progress. Our user name to add us to the project is Outwork there. "Terms of payment" Upon awarding the job, a milestone will be created for the "entire" amount owed. Freelancer will hold this money, but none of the milestone will be released until the job is 100% complete. Do not ask for any milestone payments until all the work is 100% finalized. Its important to note, that since Freelancer will hold ALL the funds, you have NO risk of not getting paid as long as the job is done properly and in a timely manner. Bid responses sent to us that are automated - will be ignored, please do not send us automated bids if you want to be taken seriously. If you would like to be considered, please make sure to read the above requirements carefully. To open the PDF, the password is: 123456
