Looking to hire a freelancer to write me a simple batch script

I'm looking for a batch (.bat) file to be written for me that handles some file management tasks. When run, I need it to:

1. Check a specified folder for wave (.wav) files and compare each one it finds to the entries in a text file I use called catalog.txt. A sample of these entries can be seen in the following screenshot.
2. If the index (the symbol before the comma) of any entry matches the name of the file (excluding the extension, .wav) the file should be deleted. Otherwise, conduct the following steps.
3. Create a new folder with a name that matches the name of the wave file (excluding .wav). The location to create this folder will be specified for you.
4. Move the file to this newly created folder.
5. Add an entry to catalog.txt in the format

[name], 0 1. 0. [filepath] 0.;

where [name] is the name of the wave file without extension and [filepath] is the entire absolute path of the file (in its newly created folder) including extension, using forward slashes not backslashes. Both [name] and [filepath] should be surrounded in double-quotes if they contain spaces.
