I have a page with a field for zip codes, that once submitted, will return a pageBlockTable with info. I'm having trouble returning a list once I submit. I'm new to StandardSetController and pagination. Any help would be much appreciated.

Here's my VF:

<apex:form >
	<apex:pageBlock title="Search by Zip">
		<apex:inputText value="{!zips}" />
		<apex:commandButton value="Search" action="{!find}" />
	</apex:pageBlock>
	<apex:pageBlock title="Nearby Company/Branch" rendered="{!zips != null}">
		<apex:pageBlockTable id="accountTable" value="{!accounts}" var="acct">
			<apex:column headerValue="Company/Branch">
				<apex:outputLink value="/{!acct.Id}" target="_top">{!acct.Name}</apex:outputLink>
			</apex:column>
			<apex:column headerValue="Address" colspan="2">
				<apex:outputText >{!acct.BillingStreet}, {!acct.BillingCity}, {!acct.BillingState}, {!acct.BillingPostalCode}</apex:outputText>
			</apex:column>
			<apex:column >
				<apex:outputLink value="http://maps.google.com/maps?f=d&source=s_d&saddr=&daddr={!acct.BillingStreet},{!acct.BillingCity},{!acct.BillingState},{!acct.BillingPostalCode}" target="_blank">Get Directions</apex:outputLink>
			</apex:column>
		</apex:pageBlockTable>
	</apex:pageBlock>
</apex:form>

Here's my controller class:

public with sharing class zipMap {

	public String zips { get; set; }
	
	public PageReference find() {
		
		return ApexPages.currentPage();
	
	}
	
	public ApexPages.StandardSetController accts {
		
		get {
			
			if(accts == null) {
				
				List<String> zList = zips.split(',');
				
				accts = new ApexPages.StandardSetController(
				
					Database.getQueryLocator(
					
						[SELECT Id, Name, BillingStreet, BillingCity, BillingState, BillingPostalCode FROM Account WHERE BillingPostalCode IN : zList ORDER BY BillingPostalCode, Name]
					
					)
				
				);
				
				accts.setPageSize(10);
				
			}
			
			return accts;
			
		}
		
		set;
	
	}
	
	public List<Account> getAccounts() {
		
		return (List<Account>) accts.getRecords();
		
	}
	
	public Boolean hasNext {
		
		get { return accts.getHasNext(); }		
		set;
		
	}
	
	public Boolean hasPrevious {
		
		get { return accts.getHasPrevious(); }
		set;
		
	}
	
	public Integer pageNumber {
		
		get { return accts.getPageNumber(); }
		set;
		
	}
	
	public void first() { accts.first(); }
	
	public void last() { accts.last(); }
	
	public void previous() { accts.previous(); }
	
	public void next() { accts.next(); }

}

Thanks in advance for your help.
