Rank Google page #1 Website - Keyword is High Competition

Hey, I want to rank my website to google page #1 results (top 3 will be best :-) with my keywords that are High Competition.

It's a French site, created in 2003.

After some google updates, my website disappeared but is always in google index.

If you can rank it to top , please show me some good proof that you have done something in past few months (you'll get for sure others jobs for my others websites )
Please, send me mail me for more information on this work.
