Hi info 110,

To increase the size of the icon to 100X100 Go to Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save all changes button:

.service-item .service-icon,
.service-item .service-icon img {
    border-radius: 70px;
    height: 100px;
    width: 100px;
}

About custom content just create the page then add your option form and set it to front page.

Thank you!
