Spanish Translation Needed for Mobile Application

We have an active, operating mobile application (iPhone and Android) that supports the construction industry. It allows users to track documentation related to call-before-you-dig tickets. The application was developed in English. The English version has also been translated to Spanish. We would like to have a capable translator review the Spanish translation for accuracy based on the English version. The app itself is relatively straightforward with about 10 to 12 individual screens that would require review.

We would like to have the work commence as quickly as possible. Our sense is that this would be less than a day's worth of work, but we will defer to your expertise. For reference, two sets of screenshots are included with this posting - one in English and our initial attempt in Spanish. If selected for this project, we would likely provide similar screenshots for the remaining pages for review. Note, the users are largely located in the Southwestern United States.

Ideally, we would like the translator to confirm the Spanish version presented as accurate and/or provide recommended edits.
