AI Scripting experts? Need some help please! (exporting layers + art-boards > new files)

[vdruts]

So I have a .ai file with many layers on separate 1920x1080 artboards; what I need is a script to export every top layer into a separate .ai file on a single 1920x1080 artboard (so I can later fix/import into AE)

*Here is a base Script* Can someone help me edit this? As this script only creates new AI files with all the same artboard/layers; but just hides the ones I don't need.

//////////////Start

var doc = app.activeDocument;

if (documents.length > 0){

    // Create the illusrtratorSaveOptions object to set the AI options

    var saveOpts = new IllustratorSaveOptions();

    // Setting IllustratorSaveOptions properties.

    saveOpts.embedLinkedFiles = true;

    saveOpts.fontSubsetThreshold = 0.0

    saveOpts.pdfCompatible = true

        if (doc.saved==false) doc.save();

        for (i=0; i<doc.layers.length; i++)

            if (doc.layers.locked == false) doc.layers.visible = false;

        fullDocName = doc.fullName;

        var param = doc.name.split('.');

        realDocName = param[0];

        for (i=0; i<doc.layers.length; i++){

            if (i-1<0) doc.layers.visible = true;

            else {

                doc.layers[i-1].visible = false;

                doc.layers.visible = true;

            }

            if (doc.layers.locked == false) { 

                docName = realDocName+doc.layers.name+".ai"; 

                var saveName = new File ( doc.path + "/" + docName );

                doc.saveAs( saveName, saveOpts );

            }

        }

        doc.close(SaveOptions.DONOTSAVECHANGES);

        doc = null;

        app.open (fullDocName);

    }

/////////End
