Checking Credit Card Date ....?

Hi friends,

I am new to SQL developement ( am .Net developer). I need to implement a stored proc in sql 2005 on CC expiration task.

I have CC exiration date.
By using expiration date (like '01/08'),

Conditions are:

1. If CC expiring within 31 days. Stored proc will write the Customer data in EmailNotification table with message type =1. (Customer will not get second notification until 14 days before expiring)

2. If CC expiring within 14 days. Stored proc will write the customer data in EmailNotification table with message type =2. (Customer will not get second notification until 11 days before expiring)

3. If CC expiring within 11 days. Stored proc will write the customer data in EmailNotification table with message type =3. (Customer will not get second notification until 2 days before expiring)

4. If CC expiring within 2 days. Stored proc will write the customer data in EmailNotification table with message type and update orderStatusID to On Hold CC Expired in order table.

My Tables are

1.

TABLE [dbo].[Order](
[OrderID] [int] IDENTITY(1,1) NOT NULL,
[CustomerID] [int] NOT NULL,
[CustomerCode] [nvarchar](12) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[DateCreated] [datetime] NOT NULL,
[DateOrdered] [datetime] NOT NULL,
[OrderTypeID] [int] NULL,
[OrderStatusID] [int] NULL,
[LastProcessDate] [datetime] NULL,

2. CREATE TABLE [dbo].[Payment](
[PaymentID] [int] IDENTITY(1,1) NOT NULL,
[OrderID] [int] NOT NULL,
[OrderPaymentType] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[PaymentType] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[CreditCardNumber] [varbinary](max) NULL,
[Last4DigitsOfCreditCardNumber] [nvarchar](4) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[ExpirationDate] [varbinary](max) NULL,
[CVV2] [varbinary](max) NULL,
[Amount] [numeric](18, 2) NOT NULL

3. CREATE TABLE [dbo].[Customer](
[CustomerID] [int] IDENTITY(1,1) NOT NULL,
[CustomerCode] AS ([dbo].[udf_FormatCode]('RS',[CustomerID])),
[Email] [nvarchar](100) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[FirstName] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[MiddleName] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[LastName] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[DateCreated] [datetime] NOT NULL,
[DateModified] [datetime] NOT NULL,
[MembershipTypeID] [int] NULL
