I'm trying to build a table using Vf combining data from two custom objects. The table will need to report on a specific record and also use formulas in the code to calculate output data.

I have some code but not sure if i'm even heading the right direction.  Any help would be greatly appreciated.

<apex:page  standardController="Professional_Service_Estimate__c" extensions="summary_table_ext">  
    <apex:form id="formId">
        
        <apex:pageBlock>
        	<apex:inputfield value="{!Professional_Service_Estimate__c.Name}"/>
		</apex:pageBlock>  
            
       <apex:pageBlock title="Estimated Professional Services Fees">
            <apex:pageBlockTable value="{!estimate_list}" var="el">
                <apex:column headerValue="Cost Breakdown - EDRC - AE %">
                    <apex:outputText value="{!el.Current_Fee__c} + {!el.What_s_Added_b_c_of_salary_escalation__c} + {!el.Added_b_c_of_Construction_Escalation_ECC__c}"  />
                </apex:column>
