You could use https://oxylabs.io/ or buy some regular VPN accounts and build a http proxy wrapper around that. Extremely cheap and works well. There’s a lot of existing projects on Github for that too.
Depends on your scale and what you negotiate. The shared nature of VPN is usually not a huge problem but depends on your use case. Most VPN providers have a better deal for bigger customers so you can just buy multiple accounts in bulk with each having for example 5 connections and use that. For US specifically it often happens that they have 100s of servers and vpn configs so you can build something out of that.
Depending on what you scrape we can help. we have proxies in 170+ countries, please get in touch at www.speedchecker.xyz , the pricing is cheaper than what you say above
