Hello Sir,
I have gone through your requirements that you want a database professional who can create scheme and ERD through visio. I can do the job as I have 2 years of experience in managing databases. I can send a screenshot of my phpmyadmin and some of ERD which i have designed.
I used to draw ERD through visio and [login to view URL] Kindly provide the details related scheme design.
Furthermore, by working together through hard work and professionalism we can get most out of this project.
Thanks
