Need someone to help me count the number of clothing items and write it down

I need someone to help me with a very simple task. Change the file name of an image, with the count of clothes that are hanging. I have around 2000 images. This needs to be done in 2 to 3 days. It should take around 30secs per image on average, so around 17 hours of work. If you can do this well, I have a lot more work very similar to this. You must be able to speak and understand English or Tamil without any difficulty and must be able to start working immediately. I can pay a bonus of 50%, and award you with more work if you can finish this within 48hrs of getting hired.
