Build a Website - Architecture Advice and Early Stage Consulting

We have a little bit of work done, in the form of a PHP, and a separate Python script, for scraping data off of two public websites. We need to think through the best development platform to build on this work or possibly re-work these scripts in a better long term development environment. We are looking for someone with good full cycle development experience that touches on system architecture, and can help us to anticipate possible future issues. If you are capable of pitching in with some development, that's fine - but we are primarily interested in setting up our development environment, defining requirements, and determining if we should be hosting our own server, and if so, configuring and administrating the server for our website/platform that we envision. Please reply with some details on your experience.
