We all know how important it is for any freelance professional to have their own page on the Internet where future clients can find the fastest contact forms to hire them (mobile phone, office phone, email, address, etc ...).
There are some professions that do not need to have a portfolio with their work online, either because their work can be seen on other websites or because their work is not online (plumbers, locksmiths, carpenters, doctors, lawyers, etc ...)
For these cases, a very good resource is VCARDS, or what is the same, electronic business cards. VCARDS are the equivalent of those rectangular cards that many of us carry in our pockets or bags to give to our clients. They are simple and customizable templates where we will put the same data that goes on our physical business card within reach of our clients but online mode. If you want, in the source link I leave you a very good article that Diego Mattei has written on this topic and in the same post you can visit a great compilation of resources about VCARDS to create yours.
