Anyone technically capable of building a v1.0 site like this and Nomadlist? (for a whole other unrelated niche, userbase and sector)

You can try

I would recommend specifying what you're looking for though. Nomad List and WIP are very different products from a technical perspective.

It's also not clear what you mean with v1.0 – I don't even know what version number I'd give WIP right now as it's been improved incrementally.
