Need EA coded with 3 custom indicators

Hello I am looking for a coder to create for me an EA out of a simple strategy that uses 3 custom indicators,

I have the source code to these 3 indicators and would like the code put into the EA so I do not have to have the indicators or give away what I use if I decide to give out EA.

also have the basics, TP, SL trailing stop option and the option to use the ATR as a stop loss. for example 1.5 times the ATR is SL so on.

Also want to be able to trade on every currency pair without having all them open, so that I set in the source code afterwards, example trade pairs (EURUSD, USDJYP, GBPJPY....) so on and all the pairs get traded that I put in the line of code instead of having to drop it onto 28 charts.

The strategy goes from buy signal to sell signal based on indicator flip, so I wish it to trade once every time the signal flips (Permitting my 2 other indicators do no contradict)

I would however like to add a trade once a day option and if enabled it takes a trade at open of new candle if in sell condition, vice versa. through something like " extern bool TradeDaily=True".

and to also choose the timeframe within the code as an external setting instead of just whichever timeframe its on. 

Tried to code myself but since I just started its not worth my struggles trying to figure it out.

Thanks !
