Coding certain cells a color - vba

Question

How do I code something to say: If the total amount is under $1000 (E11:E28) then it will turn red? Also, is there a way to clean up this vba so that it's no so lengthy?
This is a project that I want to teach my students to do as a way to do some basic budgeting.
Here is my current code:
Sub ClassroomSupplies()
Range("A7").Select
ActiveCell.FormulaR1C1 = "Week of July 2-6, 2018"
Range("A10").Select
Columns("B:B").ColumnWidth = 9.57
Range("A8:B8").Select
With Selection
.HorizontalAlignment = xlLeft
.VerticalAlignment = xlBottom
.WrapText = False
.Orientation = 0
.AddIndent = False
.IndentLevel = 0
.ShrinkToFit = False
.ReadingOrder = xlContext
.MergeCells = True
End With
Range("A10").Select
ActiveCell.FormulaR1C1 = "AMOUNT"
Range("B10").Select
ActiveCell.FormulaR1C1 = "SALES"

Range("D11").Select
Selection.AutoFill Destination:=Range("D11:D28"), Type:=xlFillDefault
Range("D11:D28").Select
Selection.Style = "Currency"
Range("E11").Select
ActiveCell.FormulaR1C1 = "=SUM((RC[-3]*RC[-2])+RC[-1])"
Range("E11").Select

Range("E34").Select
ActiveCell.FormulaR1C1 = "=AVERAGE(R[-3]C/5)"
Range("E35").Select
End Sub
Any help would be greatly appreciated.
Thanks!

Try,
'this to set a conditional formatting rule on E11:E28
with range("E11:E28")
.FormatConditions.Delete
With .FormatConditions.Add(Type:=xlExpression, Formula1:="=and(len($e11), $e11<1000)")
.Interior.Color = vbred
End With
end with
'this should get you started cleaning up the text labels
Range("A10:E10") = array("AMOUNT","SALES","PRICE PER UNIT","TAX","TOTAL")
Range("A11:A28") = application.transpose(array("Calculators","Pencils","Loose Leaf Paper", _
"Balloons","Mirrors","Axles","Wheels","Masking Tape", _
"Electrical Tape","Mini Blocks","Tongue Depressors", _
"Slinkys","Beakers","Test Tubes","Colored Pencils", _
"Lenses","Newspapers","Cardboard"))
Note that filling in a number of columns in a single row only requires passing the array into the range but to fill in a number of rows in a single column you must Transpose the array.
