Thinking about my degree show

I have had another offer for work. I have been asked by an old school friend after she had seen some of my work and asked me if I would be interested in acting as a videographer for her wedding. I am still a little tentative about doing so as I would like the opportunity to work for a closer friend or family before taking such a job on. So as of yet I have no real answer as to whether I can do it. However I have stayed in contact with her and had her send me some stuff and ideas over, in terms of what she wanted and have myself started to study the how to be a wedding videography to boost my confidence in taking it on.
