I don't think you can do that with org-latex-classes: you can define
the header part (i.e. some of what goes before the \begin{document}_
and you can define how to map headers at different depths to the latex
sectioning structure, but you cannot do precise placement the way that
you are trying to.

There may be a better way now, but in the old days I used to redefine
the org-latex-title-command variable. It gets emitted after the
\begin{document} so you can do something like this

  (setq org-latex-title-command "\\foo\\maketitle")

to insert additional stuff.
