Specific Citation Style in Latex/Bibtex

Question

I need to cite something for school in a very specific style. In the Bibliography it should appear as:

SURNAME, Name: Title. Subtitle. (X. Edition). Place: Publisher Year.

I already have it down to

SURNAME, Name, Title. Xth Edition. Place: Publisher, Year.

What needs to change is that

1. there should be a colon after the name,
2. the edition number should be in round brackets and
3. preferably the title shouldn't be in italics (although that isn't necessary)

In the footnote it should appear as:

Surname, Name: Title

I already have:

SURNAME, Title

What needs to change is that

1. the Surname shouldn't be capitalised
2. and it's missing the first name of the author,
3. as well as a colon before the title

I have used:

\renewcommand{\mkbibnamelast}[1]{\textsc{#1}} 
\DeclareNameAlias{sortname}{family-given} 
\DeclareNameAlias{default}{family-given}

to capitalise the Surname (although I only want that in the Bibliography) and switch first and last name of the authors. I am using biblatex with BibTeX backend and the style authortitle.

In full

\documentclass[12pt]{article}
\usepackage[backend=bibtex, style=authortitle]{biblatex}
\renewcommand{\mkbibnamelast}[1]{\textsc{#1}}
\DeclareNameAlias{sortname}{family-given}
\DeclareNameAlias{default}{family-given}
\addbibresource{\jobname.bib}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{key,
  author = {last, first},
  year = {2001},
  title = {Title},
  publisher = {Publisher},
  edition = 3,
  address = {a},
}
\end{filecontents}

\begin{document}
\footcite[][15]{key}
\nocite{*}
\printbibliography
\end{document}

If at all possible you should look into using Biber instead of BibTeX. All you need to do with a modern TeX distribution is to run Biber instead of BibTeX, if you use an editor to compile things for you, have a look at Biblatex with Biber: Configuring my editor to avoid undefined citations.

The necessary changes can be found in the code below with a short note on what they do. Most of this should already be explained in more details elsewhere on this site.

\documentclass[12pt]{article}
\usepackage[backend=biber, style=authortitle]{biblatex}

\DeclareNameAlias{sortname}{family-given}
\DeclareNameAlias{default}{family-given}

% family, given also in citations
\DeclareNameAlias{labelname}{family-given}

% Small caps only in bibliography
\AtBeginBibliography{\renewcommand*{\mkbibnamefamily}{\textsc}}

% colon
\DeclareDelimFormat*{nametitledelim}{\addcolon\space}
\DeclareDelimFormat[textcite]{nametitledelim}{\addspace}

% edition in round brackets
\DeclareFieldFormat{edition}{%
  \mkbibparens{%
    \ifinteger{#1}
      {\mkbibordedition{#1}~\bibstring{edition}}
      {#1\isdot}}}

% plain titles
\DeclareFieldFormat*{title}{#1}

\addbibresource{\jobname.bib}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{key,
  author    = {Anne Elk},
  year      = {2001},
  title     = {On the Theory of Brontosauruses},
  publisher = {Publisher},
  edition   = 3,
  address   = {Rotterdam},
}
\end{filecontents}


\begin{document}
\footcite[][15]{key}
\nocite{*}
\printbibliography
\end{document}
