We will select a programmer who already developed Wordpress plugins - send us your portfolio. Programmers who only send us their Website portfolios will not be considered. You need to have experience in WP plugin development. If you have any questions, please send me a PM. We have worked with lots of plugin developers in the past, so I know this plugin should not cost more than $300. So this is our budget ($250-$300). Thanks!
