I need a someone to design a circuit that has a battery bank which is charged with solar and wind power at the same time, also it can charge the battery bank from another or the same usb port, and the battery bank charges an usb device. Gives out 5V 500mAh The battery bank will be either 3,7V or 4,2V 10 000mAh. The voltage required to charge the battery bank through solar input or wind input shouldn't exceed more than 6V. All i need is the schematics, list of parts and a pcb design file. Thank you,

Hi, this is Marcos from Spain. I'm an electronic engineer and I work developing hardware for automotive and electrical vehicles. As a electrical vehicles engineer developer I've been working on development of baterry monitoring systems, DC/AC controllers and many systems of sensoring and data adquisition. For PCB designing I work with Altium and I have knowledge in electronics and electricity to work with you. You can see some renders on my portfolio of my lastest works. It will be an honour for me we can work together and I'm sure I will do a good job. Best regards.
