Design and build website for complimentary health clinic, must have excellent SEO

We are an acupuncturist and chiropractor just opened our new clinic and need a website building. It is important that it is highly ranked on google, so the worker must be very knowledgeable in this area. We also need the ability to make amendments to the website ourselves once it is finished. Prefer someone who has previous experience in this specific type of website design and will need to see portfolio We already have individual websites so information can be taken from them.
