I had a website developed that was integrated into a forum (PHPBB), basically it had a front page portal/index and some sub pages.
These pages were develeoped upon the smarty.php library where all the pages were put into template files (.tpl files). This frontend was also part of another small software and what was tying it all together was smarty.
As long as you have experience, this is copy/paste work and deletion. Hence why the budget is somewhat low, this is quick job. It's something I would do, but I don't have the time.
