Jommla 1.5 layout from a static page

Hi, we have Joomla 1.5 already installed in a sub domain of hour site (static). At the moment the installation is empty. We need to integrate to the current design (exately the same) of the static part of the site, into the subdomain in joomla. We are on a limited budget, so, please, be reasonable. Bid only if you can do the job very very quickly.
