Job Board Customization (webscribble - WebJobs Software)

Hello Experts, I have recently purchased webJobs software for a Job board. The software has been installed successfully. But, after installation, the backend is running sweet, but the front end is giving me error 500 ([login to view URL]). I need experts who configured/worked/customized webjobs ([login to view URL]) software successfully and fix that error. Also we need some more things: The site will be published for the Spanish/Latin communities in Latin America and the Caribbean, so it will be a Spanish site. We will be doing the translation of the text in the backend application of the software. We need to show a simple home page where people can search by category, zip code, city and country. We like this free css script: [login to view URL] The colors are fine; we can add later the photos and logo. I purchased the script WebJobs([login to view URL]) from webscribble and need custom layout, design and some extra features. I prefer someone that has experience with the customization of this script. I want something similar to the layout, sections and functionality of the following site: [login to view URL] 1. Need to add new header (we like the one in the script [login to view URL], also we like the style of [login to view URL] 2. Need to integrate bottom section with search options. 3. The site must have Ad Spaces for Google Ad Sense or other type of ad zones. 4. Site should be SEO friendly. This would be the first part in the project. We want this page to be considered in the near future the [login to view URL] of Latin America. You will have to provide me site name - you worked on (webjobs site)... Thanks…
