This isn’t that hard too do but I’m on another long term job. It all works but needs those final adjustments to make it mobile and desktop friendly. The site CMS is in Wordpress, There is a test page that works. All the 3D options eventually link to a shopping cart where the price is paid. It is a cool bit of work but I really do not have the time to finish it. The total budget was 4,000gbp and there is 1,600gbp left for you if you can finish it.
We’ll need to have some sort of assurance so I’d need a few UK references before we do anything. You don’t have to be in the UK but that’s where our law is.
So it’s £1600 for what I think is fair for a competent programmer, any good probably 2-3 days. There’s also some cool code in there for you.
