Hello! I'm interest in your project.
As you can see, I have a Top Qualiy C Badge. I'm in the top 1% of the C Programmers in Freelance, and I think that makes me perfect for the project.
You have no provided more information, but I consider the work won't be so hard, that's why I ensure you 7 days as a maximum time limit, I think I can finish it sooner, but it depends on the job.
Feel free to contact me if you are interested.
