Requesting someone to make an application

Hey I'd like someone to make an application for me. I'm pretty experienced in java but I haven't done anything in it for months so I can't put together how to do this in code form.

I'd like a program that could rename all the files in a directory. Now, the catch.. What I want it to do it keep the 'root' (Song name) so to say part of the file and extension. So basically for songs. Ex.

06-Song Name-som-som.mp3

I'd like it to rename it to Song Name.mp3 and the syntax on the command line to be somewhat like:

#- -som-som

First argument being prefix, and # should be regarded as any number so it could be used in a for loop so it'll get all the files like 05-Song Name-som-som.mp3, 06-Song Name-som-som.mp3, etc. and the second argument being the ending.

My 'theory'. Getting all the files in the directory in an ArrayList, using replaceAll to replace the prefix and suffix (I think it's called) unless they include # in which case it'll run the for loop to replace those.

If you didn't understand something sorry it's late, just tell me what you didn't understand in what I said and I'll explain, or if you just want more info.

To be honest I'm not even sure if any of that made sense, I'm tired, I'm going to bed.

Thanks.

I'm too much of a Java newbie to write you an app, but if you post how much your willing to pay for it you should get an answer or some PMs.

Hey I made an MP3 renamer swing app a while back... here it is http://saundersjava.zerodollars.com/MP3Namer.zip it basically utilizes the ID3 tags in mp3 files to get the artist, album, track # and such if they exist, you can also rename the files with those information in a certain order, one or all, with your own defined seperator....just try it out and see if you can get it to work to rename them go to the tool in the menu

[edit] this will get all mp3 files in the folder you open and any subfolders, and depending on how many it may take a couple seconds to perhaps like nearly a minute if you are on a really slow computer opening 1000s of mp3s
