Trademark design is also a highly professional job, which only provides professional design. Although there are agencies providing free trademark design services, it is recommended that you do not accept free design services.
If you don't have high design requirements, you can design it yourself, but if you have high design requirements, free service is unlikely to give you a professional design. If you want to make do with it, just design it casually and register. It is best not to design, just register directly in word mark, at least to protect the brand name. You will realize the importance of trademark design in the future, and you can redesign it.
Ordinary computer fonts are either too ugly or too shameful, so use them directly. We believe that unprofessional design (bad design) will only devalue your brand, not increase it.
