Over the last 9 years, I have built, by myself, a custom PHP framework, using AJAX and JQuery, and on top of it, a public-facing marketing website and a back-end web application for users to log into and use.
I am now the bottleneck of the company as I can no longer keep up with the demand for new features. I need someone to help me code, as well as a complete review of the LAMP configuration and health, as I am not an expert in those but have set them up myself.
What would you do? Hire in-house (we have no physical office, so in-house would be their own home), hire individual contractors for long-term commitments, or out-source to a large off-shore firm?
