Write some software

I need you to develop some software for me. I would like this software to be developed for Windows using Python. I’m looking for a programmer with Cryptocurrency experience and the ability to integrate with exchange’s APIs. Specifically, I need to create a trading bot either from scratch or altering an existing python script that sorta works but does many of the things I need already. Gdax is the first exchange needed with Bittrex and Poloniex next. I need a simple interface to enter in certain variables that I can easily change and tweak based on trading strategies developed. Other simple functionality will also be required.
