Where can I buy a server cheaply?
In the sea of providers that offer cheap VPS servers, it is difficult to find the right ones that are not just another "summer host company". Here is my list of trusted providers that won't get you into a lot of trouble:
VPS2Day (EU - KVM, 1 Core, 1GB RAM, 25GB SSD, 1 IPv4 = €3.50)
PHP-Friends (EU, 2 Cores, 10GB RAM, 80GB SSD, 1 IPv4 = €7.50)

Which free panel can I install on my server?
Free panels for servers that I recommend you look at:
DirectAdmin - For a little money spent, you can sleep peacefully. The fastest growing commercial hosting panel. The 60-day license is free, and after the expiration of your free license, the domains, database and the rest still remain active.
Vesta Control Panel - Simple & clever hosting control panel
Hestia Control Panel - Beautiful fork of Vesta Control Panel
KeyHelp - Nice and functional panel made in Germany
CentOS Web Panel - Yet another server panel
What is the best way to host an email address?
I do not recommend that you host your email address on a regular VPS server, so I suggest you take a look at the following services to securely send an email that will not end up in someone's Spam folder:
Zoho Mail - Free 5 users with 5GB of mail storage plan with custom domain
Yandex Mail - Free unlimited users with unlimited of mail storage plan with custom domain
MXroute - Premium email hosting with custom domain
Google G Suite - Google's premium email hosting with custom domain
Microsoft 365 - Microsoft's premium email hosting with custom domain
Where can I host my DNS records for free?
There are many DNS hosting providers, but these are some of the best (You need it for FQDN hostname and rDNS):
Cloudflare - Free DNS & CDN hosting (operates with 2 nameservers)
HE.NET - Very amazing DNS hosting service (operates with 5 nameservers)
CloudNS - Yet another DNS hosting service (operates with 4 nameservers)
