Creation of multiple individual QR-Code designs, based on existing corporate designs, on a monthly basis

We are searching for a graphic designer who is able to create totally customized QR-Code designs. As the creation of such QR-Codes is not our core business we would like to outsource this work to a reliable, creative and smart graphic designer. The task is to create individual QR-Codes, based on the corporate identity / corporate design of our clients. Of course the QR-Code must stil be readable by all well known QR-Code scanner apps after the customization. Most of the QR-Codes need to be created as pixel graphic. In some rare cases vector graphics may need to be created as well. You need to create a first edition that we review and discuss with our client. If the first edition will not meet the clients idea, a second edition needs to be created. Currently only 1 out of 30 clients is requesting a second design, so nothing to worry. Once we agreed about a cooperation it is planned to hand 10 to 20+ orders per month over to you. Our junior designer is currently working around 1 hour on one design, so it's not a big deal we think. Some works are attached to this project, that you can check the requirements in image. To find out if you are the one creative and reliable designer we are searching for, we would like to give you 3 blank QR-Codes where you can show your skills. So, this project is more like an application and you are called to quote your best price you can give permanently for the creation of a bundle of THREE (3) individual QR-Code designs.
