English - Dutch - translation of webapp - 1000 words

Hello, I need to translate a website ( [login to view URL] ) from English to Dutch. The whole text is in attachment and it's less than 1000 words altogether. First part, 500 words is a sentence by sentence translation in the format: "Add new note" => "", where on left we've got English sentence, and on the right should be a translation, The other part is "About page", also around 500 words. The order is not only about translating the text, but I would like also to get some validation after the translation is applied to the site. After getting the translation, I would upload it to the site and check if everything is OK (e.g if text's are not to long for design). After fixes, I would like the translator to look once again to the site and check, if everything looks good for Dutch-language user. The interpreter should use the words adopted in the Internet, e.g. in other similar services. Also translation shouldn't be too formal. Possible future orders.
