Assuming the job is legitimate (more on that later) it looks as if you have the bases covered if you factor jburns advice.
You didn't ask, but if you were my sealesrep and came to me with this, I would ask several questions:
Can it be done with clear substrate and printed? (If you cannot do that, then consider sub-contracting to someone like Stouse)
Does the application require the substrate color to show through? If not, it would be way more cost effective to provide a solid decal with just a contour cut shape and no weeding.
Is the deal even legitimate? Hopefully not one of those 'opportunities' we get from some scammer in Nigeria that needs 1000 of this or that and is ready to order now.
Finally, I hope you take this in the spirit intended, which is constructive criticism to help you get better and more responses on this forum. Could you slow down and write legible questions, use punctuation, and generally think through your question before writing a stream of consciousness? I had to read through your question several times to be sure I understood it and as pointed out, even the title had a spelling error. Hopefully you don't communicate with customers that way. Best of luck to you, and welcome to
