CasperJS expert needed!

Hi Freelancers! I need an expert freelancer to help me with a project for an existing website. We will share specific details to the awarded freelancer but in short you will be visiting a website, completing a search, and downloading file locally. Notes: - error handling should be with every click - full log should be generated with all process time - only xpath selectors should be used (no use of any css selectors) - no wait for (timer) should be used, all action should be based on selectors - script should be supported for any issues the following three months, after that a new contract for support will be established if required
