This sounds like an issue with the throwout bearing or pressure plate. Getting a video of the noise can help but normally any issue when pressing the pedal in is related to the throwout bearing.
Here are some guides that will help. Let me know what you find and we can go from there. If this is in fact the issue, it is a good idea to go ahead and replace the entire system because you have to remove the transmission. If you are going this far then it is a good idea to just replace everything so you don't have to go back in.
