Joomla / Virtuemart Customize

I am in need of a Joomla/Virtuemart customizing. The last guy to do it brought the whole category down and no one could purchase anything. As you can tell, my client was very upset. So we need about 4 things done. 1. field is not showing up on the [login to view URL] it stores in the database fine, but not showing up at all. 2. Products would need to have the order by the new field. 3. and...on checkout.. Have a new field with description... "?". 4. And when they are done paying it should state... "....(words here)...." Needs to start on this right away and I will select someone now. Very Urgent.
