UAV Lift Fan calculations

This project is for the calculations of lift fans for UAV (drones). I need someone that can research and specify the rotor type, diameter, speed and disc loading for a multi-copter with 4 lift fans. This would be done iteratively on 4 sizes of lift fans. (in order to assure you're read this post...please let me know in your reply the name of one of the stars in Orion's belt. I know...silly question...but it helps me gauge the respondents' mastery and comprehension of English and if they actually read the post before bidding. The four sizes of fans would be ones (in a quad-rotor configuration) that could lift 1. 100 Kg 2. 500 kg 3. 2000 kg 4. 5000 kg Fans would be ducted/enclosed. Disc loading would be somewhere between 10 and 20 lbs/ft^2. If you're able to help on this project...you'll easily be able to point out incomplete nature of this request and suggest refinements (which is ok). If I was an expert...I'd just do this myself. Feel free to ask questions. Thank you, Andy
