I need someone to code a renko EA. already been turned down as too difficult by some saying its too advanced for them

at the title says its intended for a renko chart. It uses grid and an option for martingale addition or multiplication. 

with the grid being separated into small groups as well as other trades placed sometimes continuously on each brick.

it started as a more simple version of an EA that i already have in use and had a few extras put onto it, ive been told its advanced work, and i can understand it might be.

ill put a price just so it can be accepted and posted on the list, but its open to offers as is the completion time. I want someone to work with me to offer suggestions to alter parts if you have any better ideas. Its by no means to be done exactly to the letter as written. The basic operation must be as is. that is working very well and profitably already, its the difficult fancy bits  that need adding that are the whole point of this project and that will take the time to get right.
