Wordpress Theme Customisation

The link below is our WordPress website currently being constructed using the Avada theme. And we are using Next GEN for our image gallery LINK: [login to view URL] As it is shown on the attached file, it should have functionalities such as Search bar and filter functionalities, and sidebar menu widgets and filters. With the Search Bar and filter plug-in, there should be a process where I can easily organise by folder, do tagging, catalogue all my images so it can be search and filtered easily by a potential buyer. As it is shown on the attached file, it should have functionalities such as Search bar and filter functionalities, and sidebar menu widgets and filters. With the Search Bar and filter plug-in, there should be a process where I can easily organise by folder, do tagging and cataloging all my images by batch so it can be search and filtered easily by a potential buyer. The Advance Search and Filter WordPress Plug-in can be integrated on our Image Gallery NEXTGEN. I don't mind buying that plyg-in as long it can be integrated and can do advance search and filter functions. Give me your recommendation and the reasons why you suggest to use that plug-in? Could you give me your fee quotation and the WordPress plug-in for Search and Filter you are going to use for this specific page customization, and how long it will take you to do this project. This is Part 1 of a 4 pages. If I am happy with your work, I will give you the rest of the project and more. Thanks and Regards, Zenaidy
