Market my website effectively

I am a professional violinist and specialise in playing for weddings and special occasions. During last two years my bookings went down and I need a marketing specialist to look at the existing condition of my website and give me a step by step action plan on how to improve the traffic and get the results I want.
I do not hold the rights for changing the content of my website, it is with the person who created it.
Please let me know what other info you need from me.
