Who can you recommend to build a HTML 5 landing page website for A startup that aims to attract a technical cofounder/investment?
The startup is about finding information that is not on the internet.
The website design brief is ready to go! I know I can look on websites such a Upwork, Fiverr etc but I believe a better chance of finding someone experienced that I can develop a long term business relationship with.
There are plenty of US based dev shops that do good work. You can try that. If you are looking for a CTO you should use your network. There will probably be someone looking to do something new.
