Always wanna create a site like coingecko or coinmarketcap. But does not know how and where to start. Even, does not calculate the budget. I need a figure or plan on how to start. Now things are seem complicating, does I need to learn basic web developments for management it.
Note: Not finding any developers.
First of all you should decide either you will be able to do it or not. For that you should make design, development, and important part is budget which you should made. For web design you should hire a web designer, for development you should hire a developer, for graphics you should hire a graphics designer. And from those you may get an estimate budget. To hire them you may try here or reputed freelance sites.
