Last year it was transfered from C++ pespoke site to DotNetNuke: [login to view URL], www.artfilms-digital.com. We need changes and further development work but our developer is living overseas and difficult to work with him. We are in Melbourne, working from Footscray Dream Factory (Inspire9). We would like to add a couple of functions and automations. The new developer we are looking for is Melbourne based , or able to move to Melbourne, able to work with us occasionally or initially full time, part time or on casual basis and will work with the company later on maintenance and new development ideas on ongoing basis.
