Need to create buttons that will perform certain actions

Hello, I need someone who will create script for me. I need to get 3 buttons on screen. Each of these buttons will perform one action. 1. Buy Button - immediately buy amount that I will specify when i drag the script on the chart and automatically places stop loss and take profits that I will also specify on drag. 2. Sell button which do same actions as buy button but opens sell position . 3rd button that will be there to set new limits for my position. (I will have only one position opened at any given time.) Basically when I will hit that button stop loss from my position will move to the current value minus little bit of pips(that amount will be specified later) and also will increase new take profit for certain amount of pips.
