I have a extension contrlloer for a visualforce page that i need to create a simple text class, but i'm not sure how to accomplish this. Any help would be greatly appreciated. My apex controller is below.
 

Public Class AccountExtensionController{
   private Account acct;
   public List<Bids_Sent__c> bidsList {get;set;}
   public Map<String,List<Site_Bid_Details__c>>  bidsMap {get;set;}
   public AccountExtensionController(ApexPages.StandardController sc){
       acct = (Account)sc.getRecord();
       bidsList = new List<Bids_Sent__c>();
       bidsList = [SELECT Id,IsAddedToPDF__c,Customer__r.Service_Agreement_Verbiage__c,Site__c,Site__r.Contract_Start_Date__c,Site__r.Contract_End_Date__c,Site__r.Customer_Location_ID__c,Service_Year__c,Customer__r.Contract_Start_Date__c,Name,Customer__r.Contract_End_Date__c,Site__r.Name,Customer__r.Name,Primary_Contact__r.FirstName,Site__r.BillingCity,Site__r.BillingState,Site__r.BillingStreet,Site__r.BillingPostalCode  FROM Bids_Sent__c WHERE Awarded__c =: acct.Id AND IsAddedToPDF__c=true];
    
    Set<Id> bidId = new  Set<Id>();  
    for(Bids_Sent__c bs : bidsList){
     bidId.add(bs.Id);
    }
     
    bidsMap = new Map<String,List<Site_Bid_Details__c>> ();
    for(Site_Bid_Details__c bd : [SELECT Id, Bid_Name__r.Name,Site__c,Site__r.Customer_Location_ID__c,Cost__c,Increment__c,Total__c,Price__c,Scope__c,Bid_Name__r.Service_Type__c,Number_of_Months__c,Retainer_Fee__c,Monthly_Payment__c,UOM__c  FROM Site_Bid_Details__c WHERE Bid_Name__c IN : bidId]){
        
    if(bidsMap.containsKey(bd.Bid_Name__r.Name)){
    System.debug('CONTAINS KEY: ' + bd.Bid_Name__r.Name);
    bidsMap.get(bd.Bid_Name__r.Name).add(bd);
    } 
  
    else { 
    System.debug('CREATE: ' + bd.Bid_Name__r.Name);
    bidsMap.put(bd.Bid_Name__r.Name,new List<Site_Bid_Details__c>{bd}); 
   }
 } 

}

}
