Develop a python code to do transactions on a crypto exchange

I would like to hire a python developer.

The following libraries are used:

CCXT: https://docs.ccxt.com/en/latest/index.html
CCXT Pro: https://docs.ccxt.com/en/latest/ccxt.pro.manual.html
Pandas
AsyncIO

I hope for a continous collaboration in the amount of 5-15 h per week.
The project will be realised in stages:
1 STAGE:
Currently the code has 1500-2000 lines and realizes functions similar to those:
*fetch balance from different crypto exchanges
*fetch prices
*open/close transactions
*monitor price
The goal is to implement the same functionality using the streaming and async available in CCXT Pro

Please send offers including an hourly rate and experience. Immediate start.
