We would like to ask you to create a Wordpress plugin - the simple calculator (see attachments).
* calculator placement should be determined by a shortcode position in post/page. User should see the calculator in place of the shortcode;
* depending on a shortcode the different version of the calculator should appear (see attachments);
* no need to customize the plugin on admin side. Admin should only be able to place shortcodes in posts/pages;
* the result should appear after the "Calculate" button was pressed;
* the calculator should have basic styling (CSS) - round corners on text boxes;
* you would need to write good and expanded comments in the source code. The reason is that I want to create a finance calculator myself based on your work. we just need to have nice structure to be able to go on;
We need someone who knows what he is doing (especially the security aspect of Wordpress!). Also it would be nice if you have some teaching talents - the comments should be easy to grasp.
