I would like you to create in java coding or steemjs a processor for the new Crypto Currency Blockchain "Steem" that would work with 3dcart shopping cart system:
1 On the payment screen in 3dcart there must be a checkmark option to pay with Steem.
2 If Steem Payment is selected then the USD would be converted to Steem at the current conversion price of Steem and displayed to the user.
3 When the user clicks on Place Order a connection would be made to the Steem Blockchain and the user would login with username and password on the Steemit login page.
4 The amount of Steem for the order would be transferred from the users account to another Steem account field that is embedded within the app. (That account field that is embedded within the app should be made so that it can be changed to another Steem account if need be.)
5 On success show a Your Order Is Complete screen.
6 On failure, what went wrong or how to complete order correctly.
7 Make it so that I can upload it to 3dcart as an add-on app.
Please include how long it would take approximately to build the app.
Thanks and I look forward to seeing your bid.
