Hi everyone, I just entered the market and seeking a digitizer. I'm looking for someone who can provide work in vector format. I purchased a Toyota 9100 NET and DTG Kiosk II. I'm looking for the ability to sew and print the designs. I have sent my items to 2 different companies and am surprised with the responses. One company quoted me their price and emailed me images of my artwork. The other company quoted me a price but would not provide an image of my designs. I would hope other companies would show their work before asking to be paid. I understand i'm asking them to perform work but how do I know the quality of their work if I don't see the item I sent. They referred me to their website to see other work they have performed. Well, I can also show potential customers work that I may or may not have done.

Is it normal to ask for my work to be seen before paying? I would hope so.
Also, when asking for the work to be digitized, if its in vector format, why do I have to provide sizes? To my understanding, vector format is what I want because I can resize it for any job I may have.
