I offer free estimates for my work and am looking to take input from a store user to describe what they are looking for so I can provide them with an estimate. I thought a product with an input field may be the way to go but am opened to suggestions. Either way I will need a significant field size for them to provide me with the details I would need to give them an estimate. Is there a max size for input data? Can I change the shape of the input fields on a product? Thanks!
