Find me low cost inexpensive SDR receivers that cover the frequency ranges I need

See attached video. You must be an EXPERT with years of experience in SDR Software Defined Radio sourcing and antenna design and construction and signal analysis and detection. The frequency range I would like to analyze 1Hz to 300GHz. The antennas must be directional antennas. The devices need to be handheld portable size that are inexpensive and easy to assemble and get working. And you will provide any other part information and assembly instructions I might need that I did not think of. You will provide and easy to assemble and power source that is portable and will last at least 8 hours. You will teach me how to assemble the technology, install the program, use the technology, and get it working properly. I will need to know how many SDR's would be needed and the links and pricing to all parts and they must be available in the United States. If I encounter assembly problems or difficulties you will guide me through the process step by step. You must sign my NDA before I can share any samples of exactly what I need made. I will own the copyright to all the designs, images, graphics, files, programs, source code, coding, animations, text, lists, menu's, files, files, AI access, native files, and source files. I will own the copyrights to the research, Graphics, and completed files. You will send me all the full designs, equipment resources, and source files when completed. I will release the full milestone when the work is fully completed, checked, and accepted by me. I do not pay any milestones until the work is fully completed, device assembled properly, all files delivered, all designs, all code delivered, tested, and accepted by me. You must provide all instructions to assemble, install and configure the designs to make sure it is bug free and works perfectly. You must allow me sufficient time to test each feature as you have it built and ready for me to check. If your work is High Quality and exactly what I need I would be interested in considering you for Future projects. I don't communicate on Sundays and I don't expect you to work on Sundays.
