Original T- shirt designs for Merch or Teespring

I am looking for a graphic designer to produce hundreds and potentially thousands of high quality t-shirt designs for t-shirt business. For this project I need a quality designer to supply me with tshirt designs for Merch by Amazon and other POD platforms, like TeeSpring, Teezily, Teechip etc. I will need 5 designs delivered by today and the designs need to be unique and without the use of any copyrighted/ trademarked text/ artwork. If any designs are found to be resold, the contract would be cancelled immediately. You will be uploading your designs (both .PSD and .PNG versions) to your own folder on Google Drive. For first time delivery, payment will be only after the designs are accepted by Amazon/TeeSpring. I will be needing 10 - 20 t-shirt designs per month on a consistent basis. So, this could be a long term relationship with one designer, or multiple designers if needed. For now I am open on general niche / topic but going forward I will specify certain niche idea to produce original design work based on that. Once again, all designs MUST be completely original work. Even very similar designs will NOT be accepted. We check all of your work thoroughly to make sure it is completely original. If you are found to infringe copyrighted designs, images, text, phrases and/or unlicensed fonts that aren’t available in the public domain, this is a very serious offence and you will be dropped immediately. For this project, payment will be $3 per design, aka $15 for the project, so bid only if you are OK with this requirement. To apply, please send some examples of your t-shirt designs to be considered and also mention "agreed15" in small letters in your bid which will imply you have read and agreed to the project terms mentioned here. Thanks so much for your time! I look forward to work with you.
