What VPS would you choose for a business website?

I manage a client's WordPress website, and the current shared hosting plan struggles whenever traffic increases. The client has approved a budget for moving to a VPS, but I want to avoid overspending.

I’m looking at 4 vCPUs, 8 GB RAM and NVMe storage, with a monthly budget of around $25.

Hostpro.com is one option I’ve found while comparing VPS plans. I’d prefer a provider with daily backups and support available if something goes wrong.

Would you consider this a good starting point, or is managed VPS hosting worth paying extra for when you're responsible for a client's website?
