Question – How did you hire and pay freelancers?

My co-founder and I are looking to bring some freelancers from either Pakistan or the Philippines to work with us on an extended basis. In the beginning they will be working on the landing page, and some other front-end projects.

My question to the HN community: - How can I hire good freelancers? I checked Fivvr, Upwork - but I don't want to pay per project, but rather have them work 15 hours per week. - How do I pay the freelancers? My co-founders and I are W2 employees in the US. I could transfer money on Wise, but wanted to know if there is a better way.

Thanks!
