Foobar can do it. Kind a hard for me to explain it, but I'll try my best.

- Create a folder, lets say MP3, somewhere on your hard drive which will be the output folder.
- add your folders to foobar (first just 2 or 3 to see if it's working)
- right click => convert => ... (guess you already know that)
- Output format: MP3 (guess you knew this too)
- check 'Specify folder' and give the path of your MP3 folder
- check 'Convert each track to an individual file'
- in the 'Name format' field write: $replace(%path%,'PATH_OF_YOUR_FILES',,%filename_ext%,%filename%)
- click OK

PATH_OF_YOUR_FILES = The place where you keep your folders.
