I'm a native french speaker who spend a lot of time in the website you've mentionned. I really thin I can help you to translate properly all you need to and I can give a good description of the software title without using the original description..
You'll have a good job, without any error and in the 4 days I've mentionned because I know that if you're satisfied with my job, we could work together again and it's my goal, to have a good partership and regular partenr to work with.
