Development of indicator in MQL4 for Metatrader4

I need someone who is experienced in developing custom indicators for MetaTrader4 platform. Information about the indicator I have in mind is as below: - Entry signal on current bar is based on price action, specific sets for long and short positions (e.g. positive entry if highest high of last 3 bars less than highest high of last 10 bars etc) - Confirmation of entry signals using another chart - ADX with specific values as threshold trigger - Display of spread size for the selected currency pair Entry signal based mainly on price action. I don't know whether if this is possible. If indicator works and makes profit, there is possibility of future development to automate this and winner will get all future projects to take this to the next level, e.g. Expert Advisor etc Please state your experience and any portfolio, or any proof that you have extensive coding experience in MQL4 language. Any previous work developing custom indicators or EAs is a bonus.
