Hi Jasonkbc ...
I'm PhD holder in computer applications, China, 2006, from Beijing Aeronautics and Astronautics University and MPhil in computer science, UK, 2000, from De Montfort University, Leicester.
I can do the EA for you in professional way as I'm doing MQL4 programming since 8 years, and C++ since 16 years ago. I already did more than 300 EA's during the past years where I translated famous strategies to robot traders.
Anyway, it seems to me that you are looking to make profit from Brokers lot rebate safely instead of the account profit itself.
This is can be done, but my idea is by opening as much as lots with minimal lot size and closing on bigger profit and also the sum of lots is big too.
I already did this EA to an investment big company in the past. If you like to put it on demo test to watch the results, please let me know. I will be happy to do it for you.
The EA I did is by revers engineering to a bank account that I got the investor's password ... Both accounts are put into a competition, After 2 weeks, mine wins and I win the bid to sell it :)
I will be happy for any idea or opinion for your side.
By the way, I'm not doing a lot of works on freelancer.com as I manage a blog selling my exclusive EAs.
Sincerely yours,
oshaban
