Convert script from Thinkscript to Pine Script

I have a current working script file in TOS's Thinkscript that I need to have converted to an functional equivalent script file in TradingView's Pine Script (in Version 4), including the user selectable script inputs. Once you have completed the conversion the hired coder needs to run tests with the scripts on the TOS and TV platforms to prove the same reversal indicator signals are given (and with similar and clear visual indicator markers) for both scripts for any stock symbol and for any stock timeframe. Any differences in indicator outputs between the two scripts will need to be debugged and corrected before the job will be considered completed and payable.
