lindaloustarr on "[Plugin: Contact Form 7] Submit Button Change Text"

Hi :>)
Am having an issue with getting the form button to look good, at present time we have the contact form on this page http://lorenrobin.net/contact/ in full page width set to 550px - here is current code we need to shrink the send button down, change the background color to match site colors & hopefully know where to change the wording on the button - thank you so very much for your kind reply, you are greatly appreciated :>)

.wpcf7-form input {
height: 25px;
width: 550px;
border-color: #673257 !important;
}

.wpcf7-textarea {
width: 550px;
border-color: #673257 !important;
}
