Hi,
just to clarify, you'd need all the functionality of the site reproduced into Perl-Mojo, using Bootstrap template for frontend?
That being said, do you have access to the PHP source, because it'd be obviously easier to just transcript the source, rather than inspect the site for every aspect of the functionality, in order to translate it into code...
That being said, this is definitely a job more expensive than the budget you listed, you have to implement a templating system, build the front end, and then all of the backend, so it's quite a large project to be honest, especially if you want secure, robust, scalable, and tested code base.
Let me know, if you want to have a chat about the details of the project.
Thanks for you consideration.
