A couple things I noticed:

- Validation is very slow. It was averaging out to about 5s per submission. This should be able to be done almost instantly on the front-end.

- The email input is validated with the type="email" HTML5 attribute. If you write something that doesn't pass, the notification appears (about) 400px above the form. If you write something that does pass, technically, such as "abc@abc", it is returned, by FormCraft, as invalid.

- It would be nice if the input button was clickable, although I can see that this would be more of a Bootstrap thing.

- I'm not sure how I feel about that Budget sliders reading "0-0" and, once clicked on, reading completely different numbers. If there is a minimum, why not show it?
