I need modification of an existing custom indicator

I have a customized buy & sell indicator that I would like to have modified. I had a personal indicator coded from a strategy that uses 4 indicators. The previous coder was unable to code the 4 indicators into the custom indicator so that it could work independently on it's own. I need a coder to be able code the 4 indicators into the custom indicator so that it can work without the need to have the other indicators in the same MT4 platform. It should work independently on it's own. I have all the .mq4 files available.
