# Prise de contact with Jean-Patrice Clerc

> C'est notre premier RDV (ou le 2ème, 3ème...) concernant un projet que vous avez. Nous discuterons de votre besoin, le brief, les tarifs... Vous pouvez choisir le format du RDV, cependant je vous invite à privilégier le téléphone ou en personne (région lyonnaise).
