We get asked all the time, "can y'all build X for my business?" or something similar. The answer is "yes, but ...," where the "but" is usually a rough estimate of how long it will take us and how much it's going to cost.
To get the conversation started, send an inquiry to email@example.com. It doesn't need to be detailed, just a quick, "hey, I want to talk about doing something for my business," or whatever.
We'll get back to you ASAP to set up a phone call or a face to face if you're in to those sorts of things. Picking apart the details of what your idea is is best done in person.
We're open to all inquiries, and we'll let you know if we feel it's something beyond our capabilities.
We look forward to hearing from you.
