Additions and Modifications to a EA

I have been working with a developer for over 3 months on a project and now I am not able to get a hold of him anymore so I am looking for a new developer to help me finish my EA. The project has multiple phases and we are at the last and final phase of the EA. 

The EA is very math oriented so please only apply to this job if you have math skills and knowledge. 

This last update to the EA contains adding new elements/indicators to the EA along with modifications of previously added elements and indicators as well. 

The EA is a bit complicated to understand and has been worked on by the same developer for a while but he did code it in a way where he said most developers can understand. 

I will not post any details about the EA here until I find someone i want to work with as it is unique and valuable information that i own the rights to. 

Please only apply if you understand EA's very well, have worked on big multiple phase projects/ea's and are good with math. 

Payment will be done in increments of the assignment meaning if we have 20 items that we need done then we will set a goal to obtain 5 once those 5 are done we will pay and then move on to the next set and so on.

Thank you
