Above 3 are expensive though, but as an Individual you can choose Winnower for $ 20 which is growing: (The Winnower is founded on the principle that all ideas should be openly discussed, debated, and archived. ) https://thewinnower.com/ and if it of good quality try a really cool place Science Matters (Science-matters is delighted to announce the launch of Matters, a new, open-access journal series dedicated to publishing single observations.): https://www.sciencematters.io/

Best of luck in submissions!

Thanks,
