Do about 30-40 Simple technical Illustrations

Hi, for a Power Point Presentation and a printed Workbook I need several Illustrations (in Vector Format). Until now I did them myself or got Pic's from Stock agencys or images from Wikipedia which were under a free license. Now I want to get all the illustrations in one style and better looking then I can do them myself. You will get from me my illustrations or sample images and explanations and instructions how to do the illustrations. Technical understanding of digital Photography is a plus. I don't need fancy stuff. Simple and good looking and a clean and good style is enough. I need a continuous style of all illustrations you do! I attached some illustrations you should do as a sample, so you can see for yourself. I will need you in the next six months for about 50-100 Illustrations. I guess once a month I will need 10-15 of them ... I have no idea how much time one needs for this. I need myself between 10-30 Minutes for one, but have absolutely no experience, so I guess you time will vary between 5-30 Minutes depending on your efforts. If you want to get into this project let me know an estimate what you thing you need per illustration. I honor honesty with continued work... I have freelancers working since ten years for me... Some samples of your work would be great. If you want to you can use the attached samples to give me an idea how you would handle my job. This is greatly appreciated. I attached three images. Form easy to complex 1- Light entering a Sensor and Signal is send to a Analog / Digital Converter. Here I would need a nicer representation of the sensor and the A/D Converter 2 - Different Camera Histogramms. Here I would like to have more real life looking Histogramms, like on a Camera Back. But a simple representation would be ok. 3. Bayer Pattern - This is a illustration I would need to be redone as it is, but a bit (only a bit ) nicer and with the copyright by me. (As this image is only free to use for non commercial purposes) Ok I hope you understand my goal, if you have questions, just ask. The project settings Budget and Time wise, are discussable. Let me know what you want and if I see cool references and good samples we can find something that works out. Thanks for your offers.
