Hi there, I'm Matt and can help you with your website charting project. I understand your general idea though would like more details of the final website implemented.
Relevant Skills and Experience
23 years as IT developer and webmaster, multimedia work as editing, changing and scripting. Last 5 years mainly doing web animations/visualizations with HTML5, SVG and javascript (GreenSock, D3.js).
Proposed Milestones
$1600 AUD - First month of development (draft application, APIs)
$1600 AUD - Second month of development (charts, aggregates, etc)
$1600 AUD - Third month of development (final functions, tests and optimizations)
Waiting for more information for a choice of dedicating almost all time for next 3 months exclusively for this project (paid nearly 2 times less than usual here in Slovenia).
For any technologies that I don't have them in my little finger I will quickly learn and adapt.
Regarding cryptocurrencies I have general knowledge and enough financial terminology (worked as Internet Security System Engineer in the bank for 6 years) to know what charts to implement as well.
Best Regards,
Matt
