Hi! We are looking for some wordpress guru and would be able to create wordpress plugin for our aplication. We have online booking app for our clients and we would like to create and add it to free plugins shop. The only function we need is to open external url in popup modal iframe. Client who will use the plugin, will be albe to add button anywhere in page with some class and url of their Booking engine (our app). Pop up modal should work on desktop and should be deactivated by default for mobile devices smaller than 1000px width.
