Well the first hurdle is just getting people to communicate regularly and decide on a site, leader, game plan, etc. The next hurdle will be essentially insurmountable unless we have an enormous quantity of initial startup capital ala-SpaceX, Blue Origin, etc, because even getting a man to perform a single or a few orbits demands a launch vehicle on the scale of Atlas LV3B, that is we would need a rocket with dimensions of around 3m diameter and 28+m height, producing a sea level thrust of 1800kN+ for 135+ seconds, and sustaining 3-400kN for up to 5 minutes. I'd say use kickstarter sites, Youtube channels, and other social media platforms to source donations in the millions to tens of millions, that can and has been done, however projects like Copenhagen Suborbital aren't trying to send a man into orbit, just into space, this hypothetical project would be much more ambitious as the delta-V required to get a man to orbit is considerably greater than just to get a man to 100km+ altitude. Assuming the necessary people are gathered to form a competent team and the necessary funding is flowing in you need to actually construct your rocket, so you'll need significant CNC and milling machinery to build things like 3m diameter aluminum or steel rings for the rocket's body, structural ribs, panels, the capsule, fins, etc. You'll need to source tanks either rolled purely from metal or possibly special order COPVs if you want to reduce space and try for high engine performance by storing your propellants at very high pressures. You'll need a workshop with the necessary dimensions to at least shield your rocket and machinery and assembly equipment like cranes and gantries from the elements, maybe not a cleanroom but at least four walls and a roof. This could go on for pages but you get the picture.
