Hi,
I have a few questions about the project. Do you want a custom branded blockchain explorer powered by the Insight code, or are you trying to integrate Insight into your own API?
I can help with either, but I would need a little more information about the project. I'm new to Freelancer and can work with Node.js, and Angular, and have built bitcoin applications using web API. I'm currently also working on a bitcoin project for the Coinbase Hackathon. I'm willing to work for lower to build my reputation on Freelancer.
