Contrato profissional para criação de site de cadastro de pousadas/hoteis

Hi. We are a Romanian company that produces clothes for children. We are interested in a collaboration regarding the making of tailoring patterns for children's clothing, patterns made after photos.
We would like to know in which CAD system you are working and if you can give us an informative price for a product like this. We would like to say that we want a long-term collaboration. Thank you very much for an answer from you.
