HELP-Pattern needed Sewing Machines Parts and Sales in Los Angeles

A close family friend offered/wants to sew my wedding dress. But she's not comfortable making something without a pattern. She did say she can mix and match patterns. I tried dresses on to figure out what I liked and this is what I want. I want the runway version as I'm in love with the overlay and need the softer bottom to go with. http://imgur.com/a/vmcud I'm not a sewer at all and I'm finding very limited pattern options. Any suggestions??? Less than 6 months before the wedding and I'm starting to stress.
