Scalable VPS for SaaS Blog?

[Hugesierra]

Hello, I’m building a SaaS-focused blog and expect traffic to grow over time, so scalability is important. I’d like to start with a VPS offering around 4 vCPU, 8GB RAM, and SSD or NVMe storage, with the ability to upgrade easily. Budget is $50–$70/month. USA location preferred. Also interested in providers with good uptime and support. Any reviews on Exmasters.com VPS hosting services? What vps host is better?
