Bigcommerce Translation

We are in the process of creating a website aimed at Spanish speaking [login to view URL] task will involve the translation from English to Spanish of the navigational link buttons, standard messages and user instructions found in the Bigcommerce software . For example, the "Buy Now", "My Account", "Quick View", "Out of Stock" buttons/message will all need to be changed so that the native Spanish speaker can have an authentic shopping experience. These phrases/details may involve working in the site's HTML, CSS and PHP database. The selected applicant will need to: 1) Identify these English words/phrases/instructions referenced above 2) Provide us with this list for translation (It would be a plus if the successful applicant knows Standard Spanish and can do the translations) 3) Replace the English text with the Spanish equivalents
