Convert SQL to LINQ to SQL

Question

I'm having great trouble in converting the following SQL to LINQ to SQL, any one able to help out?

SELECT     dbo.ExpensesGroup.ExpenseGroupId, dbo.ExpensesGroup.Title, SUM(dbo.Expenses.Amount) AS TotalAmount, MAX(dbo.Expenses.DateLastTickled) 
                      AS LastTickledDate, MAX(dbo.ExpensesGroup.DateTime) AS Date, Username
FROM         dbo.Expenses INNER JOIN
                      dbo.ExpensesGroup ON dbo.Expenses.ExpenseId = dbo.ExpensesGroup.ExpensesId
WHERE     dbo.Expenses.Status = 'AwaitingApproval' or dbo.Expenses.Status = 'AwaitingApprovelGrouping'
GROUP BY dbo.ExpensesGroup.ExpenseGroupId, dbo.ExpensesGroup.Title, dbo.Expenses.Username
ORDER BY MAX(dbo.ExpensesGroup.DateTime) DESC, dbo.ExpensesGroup.Title

Or even better anyone know of an automatic SQl to LINQ converter?
