Looking for a freelance Blocs Web designer to update website

We’re a music band. We have made our website using Blocs but there are some issues. It doesn’t render well on all formats. So we’d like an expert to have a look and tidy everything up;
And we’d like to update it with some specific pages (e.g: an access to a hidden page with downloadable content, page protected with password and asking for email too for access).
Actual site : www.braveryinbattle.org.
We’re Paris-based.
