Sobi2 (Joomla) customization

We have a Joomla website with a SOBI2 Directory installed. We need to customize: 1. Entry Form: Should be arrenged in tab style: e.g. 5 tabs: [login to view URL] Info, [login to view URL], [login to view URL], [login to view URL] Category, [login to view URL] Images 2. Make a contact form for each entry. Where E-mails are send directly to the listed companies and one CC mail to admin. 3. Modify design and look of entry form, category view and detailed view of SOBI2. (simple CSS, e.g. border colour, spacing etc.) 4. Make sure SOBI2 works fine with Community Builder (a CB Plugin is already installed to automatically transfer entries to CB)
