Hello there,
I can help you out to move your website to Magento 1.9 and use the RWD theme. But the price, time-frame etc. it all depends on what you have currently.
If your current website has register form and registered customers, we can transfer the customer's data to Magento.
Please share an url of your current website, so I can have a look what you have and please make a list of the things that you want transferred on your Magento website.
