127852 Affiliate software changes

I need some modifications done to an existing affiliate software. I want it to opperate as a straght line forced matrix so that everyone that joins them is placed in one after the other in one straight line down, rather than having to have a width set. They way it is currently is that in the admin area you set the width and depth of the matrix, the software has to opperate at a minimum width of 2, we want to change that so that it will opperate at a width of 1, so it forms a straightline downline, i.e. Level 1: 1 member, Level 2: 1 member, Level 3: 1 member, Level 4: 1 member, Level 5: 1 member, and so on all the way down. Please include the total cost and time frame to complete the project.
