osCommerce Language files translation required : Spanish or Italian

For those who do not know, osCommerce is a shopping cart system with the majority of the english language text already pre-translated to French/German etc. The more you change the osCommerce system from the standard build, the more bits need translating into the non-english language. Thus I have several .php files which you will need to check and compare, in order to provide translated text. The work is pretty simple, but you will need to know some basic HTML to be able to insert grave/acute/etc. accents into the translated versions. The filenames will all stay the same, the capitalized text will all stay the same, you will only need to translated the incorrect text in the single quotes. You will have to compare the existing english files (which have been zipped up) with the non-english files and make corrections/rewrites as required in each file. All quotes (apostrophes etc.) within the text will need to be escaped with a backslash. Quick work for a GOOD Spanish or Italian speaker. I need this ASAP - do not bid if you cannot deliver in 3 days of acceptance.
