Develop place to buy our crypto token through our website (SMART CONTRACT)

We have our cryptocurrency, Simmitri (SIM) that is already listed on 1 exchange - Exrates - but we would like to have the ability for web visitors to purchase directly on our website as well. You will see in the attachment that we are trying to have the options go through TypeForm which is integrated with Stripe, but if they select "Bitcoin or Ethereum" it will redirect to the Coinbase Commerce processor. Since having the token listed on an exchange makes the price fluctuate, you'll need to pull the latest price into the order forms from Exrates API. Additional API docs for Coinbase can be foun d here: [login to view URL] If there is an easier way to do all of this we're open to it. But the main purpose is to simply sell our tokens through the website without having to go to the exchange(s). important: you have to finish this project in a week. It will apply to someone who concrete solution plans and will pay $ 1000.
