Question
I would obviously pay them if/once the idea took off, but I don't have the capital to do so now.
Answer
Get on Fivver and upwork ASAP. Find someone in India or Pakistan who has the skills but works for a lot less money. Social media requires a base of people to build it out so you need to also get out there and prime people for this new platform by basically “pre selling” the idea. This does two things, 1. It gives you the audience you need for beta and 2. It gives you a crowdsourcing base for money. Get on telegram. Join the groups. Talk about it on there because those guys are desperate for a new platform. Get on Parler. Engage with similar companies doing what you want to do.
