Salesforce Lighting Web Components, Google Map and Custom List view for Digital Experience Public Website

I'm looking for an experience Salesforce Developer to create LWC's for use on a public Digital Experience Site. Guest users don't have accounts, simply access the live website. These components will be positioned on a custom object record page. 1) A component that lets the Admin select a field from the custom object and displays the value of that feild for the record on the page. There should be two other inputs on the component that enable the Admin to enter a CSS class name for the component and a title to display above the field value. 2) A Google Map that displays a pushpin based on the UK postcode 3) An image carousel that pulls in image files stored on the record. In addition I would like two custom list components to display on the custom object list page - again for public Guest users. One list view should display results in a grid format, the other in a list view. All custom HTML should be responsive and where possible use the Salesforce library. Search functionality is also required on the list view page. I've had one false start on this project with a developer taking x4 times longer than quotes and without the relevant skills. For your proposal to be considered, please share specific examples of projects that have been undertake that match my requirements. Also include an accurate time and cost estimate.
