I am working on designing a site for a client who wants to create an online music school. The client wants to keep the site very professional with an academic design which would enforce trust. However I was wondering since this school is going to be online ( It does have a physical address which is the address of a famous recording studio in Hollywood and is going to be run by a well known band which has been around for like 30 years ), would a distinctive call to action button make it seem like a commercial venture like other online schools (with no focus on quality) and reduce its impact.
The screenshot of the rough wireframe is given below:
I looked at Berkeley's online school for music and there is a call to action but it just refers to when classes start. I cannot use this approach since the band members want it to be a self paced study with help on demand as needed.
