Pre-made logos
If you choose to go with "pre-made logo" then it means you choose a style that has been designed and it's adjusted to your names, letters and date.
Custom Logos
If you choose to go with "custom logo" that mean that I design a logo only made for you. I usually use the letters in your first name and twist them somehow together. It can be different fonts I work with and in some cases there is graphic like leafs added to iy.
