DKode, you will probably want to do a lot of reading on this site. There are a few thousand things that you'll need to pull that off. First off, you need to decide what is important, and what is fluff. Then from the important things, what is 'vital' for the functionality, and what is 'nice' to have for functionalilty. I suggest visiting theSuper Search node and start to dig and read.
I know that it's great to want everything, but you actually want this to be done in multiple stages (if done in house.) So you will have to identify exactly what needs to be delivered with the first version. If the budget allows, vroom is your best option. (I'm not sucking up, I'm just stating the obvious... look around at PM just look at the creation.)
My last piece of advice is to do baby steps into this larger project. It seems to me that you've not used SQL, so I can assume that DBI is foreign to you as well. I'd start with implementing a small CGI DBI that stores, retrieves, updates, and removes data. This would be a good project that will help you determine just how much work this is going to be for you. Finally, keep communicating and participating here at Perl Monks. You'd be suprised just how much you learn just by reading other people's questions and comments. Good Luck!
Snippets of code should be wrapped in
<code> tags not<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
