Convert simple indicator into funtion that can be used in EA

Hi All, I have an indicator which does some calulations and plots a series of lines, these lines are used to indicate order entry points ..  The problem is that when I drop the code into an EA as a function I get the normal buffers / array out of range errors due to the difference in the way an indicator and an EA works.  On further investigation it looks like the conversion will take me a while so I am looking for a coder that can convert the indicator code so that it will run as a function in an EA, I just want to drop the function into the bottom of the EA and call the function from the relevant part of the EA and take action based on the variables that the function sets. I also want to have the same lines drawn when the EA runs both live and in the strategy tester.....  Should be failry straight forward for someone that has done this before.  I need quality work, all coments in **English and a quick turn around.
