I agree with the others above and add the following comments:
*"Moulding" or "molding" are interchangeable. The one with the "u" is the British spelling while the other is more the American spelling.
*"Vacuum" has one "c" in it.
* I would change this sentence, "If you allow me the chance to detail your automobile i will treat it as if it were my own" to something like, "Give me the opportunity to detail your automobile and I will treat it as if it were my own". Its more assertive.
* You need more pics, if even of your own car. People like to see the whole vehicle, not just fancy reflections. Show the car from every angle. You're selling an engine cleaning package so include a pic of your super clean engine.
Yeah, it needs more work but its coming along fine. Some minor refinements and you'll be set.
