We currently use Joomla 1.0.10 and have two components that work together from the end users point of view, but do not work together from the admin point of view.
There is a directory component and a forms component.
Here you see the directory.
[login to view URL]
then when you click on the Information Request icon, you see the form.
The way it works is that there is a link we place in the Directory component that tells what form to go to. But we also need the form portion of the component to be part of the directory component.
I might need to send you the code/component so you can see how it works before you can really bid on this.
