I'm trying have a line that spans the width of the page after my name and title. Something that looks similar to this:

I am hoping that there's a document class that will allow me to do it easily, however I've been unable to find anything so far.

For a generic title-separating rule you can use

\documentclass{article}
\title{My title \endgraf\rule{\textwidth}{.4pt}}
\author{My author}
\date{\today}
\begin{document}
\maketitle
\end{document}
There's also a patch of \@maketitle possible via etoolbox:

\documentclass{article}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\@maketitle}% <cmd>
{\vskip 1.5em}% <search>
{\rule{\textwidth}{.4pt}\par\vskip 1.5em}% <replace>
{}{}% <success><failure>
\makeatother
\title{My title}
\author{My author}
\date{\today}
\begin{document}
\maketitle
\end{document}
And then there's also just a straight \underline:

\documentclass{article}
\title{\underline{\makebox[\textwidth]{My title}}}
\author{My author}
\date{\today}
\begin{document}
\maketitle
\end{document}
Alternatively, you don't really have to use \maketitle. You can just create your own title that matches the original definition of \@maketitle in article.cls:
\def\@maketitle{%
\newpage
\null
\vskip 2em%
\begin{center}%
\let \footnote \thanks
{\LARGE \@title \par}%
\vskip 1.5em%
{\large
\lineskip .5em%
\begin{tabular}[t]{c}%
\@author
\end{tabular}\par}%
\vskip 1em%
{\large \@date}%
\end{center}%
\par
\vskip 1.5em}
\fi
So, for example, perhaps something like:

\documentclass{article}
\begin{document}
% Your title here...
\vspace*{2em}% http://tex.stackexchange.com/q/33370/5764
\begin{center}
{\LARGE My title \par}
\hrulefill\par
\vspace{1.5em}
{\large My author \par
\vspace{1em}
\today \par}
\end{center}
\par
\vspace{1.5em}
\end{document}
...and obviously many more options...
\author{\makebox[\dimexpr\textwidth-2\tabcolsep]{\underline{\makebox[\textwidth]{My author}}}}. The difference between the \title and the \author is that the latter is actually set inside a tabular; so there's \tabcolseps involved.
