254213 PHP developer needed

Hello, Im looking for a PHP Developer who could resolve some small bugs on a current opensource helpdesk (from [login to view URL]). Im looking for someone who could be available IM (Skype,MSN,GTalk,Yahoo). Some of the bugs are the following, - Fix "Catchable fatal error: Object of class stdClass could not be converted to string in /folder/class/[login to view URL] on line 72" when enabling FetchMail Configuration. It seems this eror is because [login to view URL] was designed for PHP4 version, we are currently using PHP5. - the emails does not show up correctly when someone non-registered reply to a opened ticket over email. - make helpdesk to send emails using PHP SMTP function. - Staff signature when reply to email from help desk does not show up, add Staff signature function. - when someone use our signup form the purchase gets redirects to our helpdesk, the ticket its showing <b> char's on it, we need to make the ticket to show up properly. - send small notification to customer when someone closes a ticket. * Lowest bid will probably win this.
