Google Sheets Apps Script Gury

Hi I need a google sheets Apps script Guru who can hep with the following: I will create a google sheet and save it in my google dive in some folder. this folder will have 3 CSV files. Upon launching or using some button I want to import the CSV data into 3 tabs Once imported I want a line graph creating Sheet 1 & Sheet 3 (if it exists) >> Sheet 1 and Sheet 3 layout is the same except the values.. if sheet 3 exists then overlay the graph already created from sheet 1 I reckon this is 2 hours worth of work for someone who knows what they are doing. I have an example here [login to view URL] 3 sheets are imported manually.. graphs are also added manually. I want to create these at the touch of a button if possible
