I am looking for a freelancer to help me create a re-usable contract between our company and U.S. real estate and business owners who will allow us to install our wireless telecom hardware at their location(s). The host provides the electricity and (usually the internet connection) and we pay the host, typically based on the amount of data traffic. The ideal candidate should have experience in contract drafting and be familiar with the specific requirements and considerations related to internet-connected hardware installation. This contract should cover all necessary terms and conditions, including but not limited to payment terms, liability, and confidentiality. The freelancer will need to collaborate closely with me to understand my specific needs and tailor the contract accordingly.

I would like to have a consult regarding the following circuit - https://longview.be/basic-rf-over-fiber-laser-driver.html I am attempting to integrate it into a LiFi project. Ultimately I need to use an LED as the transmitter. I understand there is a significant difference in bandwidth. The incoming RF signal frequency will be in the 2-100 Mhz range. Instead of taking the circuit apart and redesigning it, I am wondering if it is possible to allow the circuit to perform the modulation and then amplify the output. For example - If I was able to construct the board, could I do something like the following (assuming supporting circuitry were designed) - Connect a laser diode like this - https://www.lightoptics.co.uk/products/1310nm-coaxial-3mw-dfb-laser-diode-fiber-pigtail-fc-apc-connector To a photodiode like this - https://www.lightoptics.co.uk/products/1550nm-photodiode-coaxial-fiber-pigtail?pr_prod_strat=e5_desc&pr_rec_id=dda712133&pr_rec_pid=7869658857730&pr_ref_pid=7870182555906&pr_seq=uniform Then connect the photodiode to a transimpedance amplifier like this - https://www.ebay.com/itm/155797335155?itmmeta=01HVKG8FNC6EMC7QHDC2BW0RQS&hash=item24463eac73:g:LsYAAOSw6pRlEvLw&itmprp=enc%3AAQAJAAAA0G7waUPGWl36fMiTU8xff9f09lO1rmx8hWpaRpi%2FYWOuz5AQMr0VAiF7f%2FcoeBbWiUROzJx1F%2BRB17mFrPo5x1lqWBUO%2BLZoVRlglNf5i1ev3CIvf6YF5WeXfmQYrUyy6AzWgPSxZzUwjv4x5rVXDBhGcUqvPA9ffGzLpDUqiJ%2B66Ggw69kBpyRqBAFbM0CpkzdqY5BnmGq2VyVc%2BcWFjbPl4Y7aXotYCc21Kwx52q1JmVLJqsf4n7aKkl6OwAqyW8I1kDWQNUh0u3mP2SPcwvM%3D%7Ctkp%3ABk9SR-D6ofDcYw If that is usable, could the output from the amplifier be combined with a power supply to modulate an LED to use as a LiFi transmitter? What size/power LED's could I support? I am also open to alternatives. This is what our call will focus on if you would like to participate.
