Joomla site upgrade (incl. JomSocial, jNews components) and hack fix needed

For someone who is an expert in Joomla this should be very easy. Please provide proof of your skill in your response. The following needs to be done: * Upgrade Joomla from 1.5.13 to 1.5.25 to be compatible with the hosting server's PHP 5.3.3 * Purchase and update the current template from 1.5.18 to 1.5.2 to be compatible with the updated Joomla 1.5.25 * Purchase and update the JomSocial component from 1.0.125 to 2.4.1 to be compatible with the updated template * Update the jNews component from 1.2.0 to 7.4.0 to be compatible with the updated Joomla 1.5.25 * Following the upgrade, ensure no more bugs in Joomla, JomSocial and jNews * Ensuring E-mails are working * Ensure the hack on the sign-up flow is working (hack is to have confirmation e-mail sent to administrator rather than user so that administrator can accept or reject the application) * Ensure the layout of search page and layout in general is correct I will provide you with FTP and db access. The upgraded working Joomla site must be installed on the client's server and existing user data must be kept (i.e. must work with the upgraded site). Thanks.
