Hi,
I am an expert in elearning systems and development with over 13 years of experience and would be happy to work with you on this project.
I work only on flat rate as I work on irregular hours an have a team that can work together.
My rate here is $400, installing the latest version (2.5.2, so far) with Portuguese-Brazil as per your request.
If this is satisfactory so far, please let me know so we could commence discussion about your project.
Best regards,
