Upgrade?

I started my website in 2009 with a package my daughter bought me for my Christmas. The company recently offered me an update to their latest 'drag and drop' website builder and they would do it for a small fee, which I paid. The next day they emailed to say they couldn't do it as it was too much work, but they would refund the money and i could do it myself. So now I have to the end of the year to transfer the website (over 1000 photos) before I make it live. So quite a daunting challenge as there is no fast way to do it, but the website builder is so much better than the creaky one I am using at the moment...
