Custom Signs FAQ
How do I get a quote?
Call us or use our contact form with what you need, the size, quantity and your logo or artwork. We will send a free quote.
Can you design my sign?
Yes. Send us your logo and wording and we will lay it out.
What file types do you need for artwork?
Vector files like AI, EPS, SVG or PDF are best, especially for cut vinyl. High-resolution JPG or PNG files work for printed items. If you only have a low-quality logo, we can help clean it up.
