With a budget like that, without any SYS Admin knowledge, you would be going for first tier cloudways for Cloud hostingI am going to choose a package with low hosting costs like say $10 - $15 a month or something.
@zfc, hosting from Contabo is still also hosting.If you use hosting, you will constantly encounter restrictions. I would buy and use the vps from Contabo for 6€. I would set up Aapanel and open as many sites as I wish.
