I also checked some vanity address generators but they took so much time and your guide lack some pictorial representation so if you could add them it would be great for newbies like me
If you want to generate a vanity address, the best tool for doing so is this one:

If you are desperate for a vanity address but cannot generate one yourself, there is a method called split key generation where someone else can generate one for you trustlessly. It involves you generating a private key and then giving the associated public key to the person who will generate the vanity address for you. Based on this public key they can generate another private key which will lead to the desired address when combined with your own private key. Only you will know both private keys so only you can access the address.
