Incrementing folder name script? help...

Question

Here is the thing, im into tethering mode in my nikon camera (Picture talk/transfer protocol) in which it automatically saves every shot into a "hot folder" (~desktop/images) i've got my action to automate 4 pictures to be posted into a 4R size contact sheet, saved as jpeg, and closes the window. though the hard part is, i can't figure out how to automatically script it so that after saving and closing the contact sheet, all of the four raw jpg  shots + the newly saved contact_sheet.jpg file would be foldered into a subfolder (inside ~desktop/images) which generates a unique/incrementing folder names everytime. And so, i could continue shooting, and every after 4 shots, i could use my action+ the given script so it automatically does the foldering for me. Below are some examples of what's inside the "image folder" looks like.
above is the ïmage folder before the script should work
above is how the script should work, then after, if another 4 shot has been taken, i could execute the action to make and save the contact sheet and hopefully, if i would use the script again, it would put these five new *.jpg files to a incremented folder name like "Contact (1)" then for the next batch "Contact (2)"... and so on...
Can anyone help me please? Tnx!

I think creating that folder comes close to this, with a few adjustments. I really understand a few in scripting and so I hope someone could help out..
function createFolder(file) {
  var parentFolder = file.parent;
  var saveFolder = new Folder( parentFolder + '/' + file.name.substring( 0, 8 ) );
  if( !saveFolder.exists ) saveFolder.create();
  var saveFile = new File( saveFolder + '/' + file.name);
  if( file.copy( saveFile ) ) file.remove();
function main() {
   var folder = new Folder("~/Desktop/images");
   var files = folder.getFiles();
   for (var i = 0; i < files.length; i++) {
     var f = files[i];
     if (f instanceof File) {
      createFolder(f);
main();
