Can't move footer up on page

I'm trying to write a letter using the scrlttr2 document class. My footer is 3 lines and as such is touching the bottom of the page. I've been trying to move the footer up by using the geometry package (varying footskip and margins) but I'm not having any luck. Any help would be appreciated: my code is below. I should mention that this is a template I found on the internet that I have been trying to edit.

Thanks

\documentclass{scrlttr2}

\usepackage{fontspec} % Allows font customization
\usepackage{marvosym} % Allows the use of symbols
\usepackage[english]{babel} % Required to compile in Windows

\setlength\parindent{0pt} % Removes all indentation from paragraphs

\defaultfontfeatures{Mapping=tex-text}
\setmainfont {Garamond} % Main document font
\setsansfont {Garamond} % Used in the from address line above the to address

\renewcommand{\normalsize}{\fontsize{12.5}{17}\selectfont} % Sets the font size and leading

\setkomavar{fromphone}{(000) 111-1111} % Your phone number
\setkomavar{place}{} % City written before the date, put your city here if you want this
\setkomavar{signature}{John Smith} % Your name as you want it to appear in the signature

% These are not used in this document, uncomment if you would like to use them and refer to them as \usekomavar{name}

\opening{Dear Recruiter,}

PARAGRAPH ONE: State the reason for the letter, name the position or type of work you are applying for and identify the source from which you learned of the opening.\\

PARAGRAPH TWO: Indicate why you are interested in the position, the company, its products, services - above all, stress what you can do for the employer. If you are a recent graduate, explain how your academic background makes you a qualified candidate for the position. If you have practical work experience, point out specific achievements or unique qualifications. Try not to repeat the same information the reader will find in the resume. The purpose of this section is to strengthen your resume by providing details which bring your experiences to life.\\

\end{letter}
\end{document}

• Do not use \\ to get a blank line. If you need a parskip instead a parindent set the KOMA-Srcipt option parskip. Then \setlength\parindent{0pt} should also be deleted. Use \setkomavar{firsthead}{...} instead \firsthead{} and \setkomavar{firstfoot}{...} instead \firstfoot{}. Replace Sincerely yours, \\ \\ \\ \usekomavar{signature} by \closing{Sincerely yours,}.
