Hi,
I have worked on such projects in the past.
I rent several dedicated servers and I have high speed internet connection so I should be able to quickly download the videos for you.
Due to various protections and rights management schemes employed by websites, I'll have to check the website in question before guaranteeing that the files can be retrieved. Please contact me with the details mentioned, I'll be happy to check it out and give you a better answer.
Thank you,
Marius
