Amendments to a Directory Press website

I need some changes doing to this website. [login to view URL] Its a Wordpress Directory Press website. The website has almost been finished but there are some things need doing to complete. Here is a list. 1.) Search, the search isn't working properly. It needs the location to work, at present it 404's. 2.) Events page needs a calendar. It maybe scraping the events system there and using an Events Manager plugin which i downloaded but ideally it needs to integrate into the My Account to let customers upload events and have let visitors use the "Add to Calendar" button. This is a decision I need help with. 3.) Vacancies page, needs a closing date whereby the vacancy will be removed on this date. 4.) On vacancies again, need the vacancy to form to send an email directly to a employer, so need to add an email address via the CMS in the Listings page. Maybe as a custom field or something. This project will require some additional work as we go along. Also will lead into other projects. Look forward to your replies. Thanks Anthony
