Website development (Wordpress & Advanced Custom Fields)

We need a developer who has experience with WordPress and extensive experience with Advanced Custom Fields to ADD FUNCTIONALITY to a page. The finished product should be able to (see images for clarification): -have added checkbox functionality for all Elective Units -The unit code should be visible before all unit (Core and Elective) and ordered in alphabetical order -Within the Elective Units, this field should have the option to be split and duplicated to an infinite number (eg Group A, Group B, Group C). This will be different for each Qualification so we will need to be able to select how many groups for each different Qualification. -The user should be able to select a MAXIMUM number of Elective Units based on the above criteria (see photos). This will be different for each Qualification and will be decided by us. If there is more than one Elective Group, this maximum value will apply to all Elective Groups. -For each Qualification, we should be able to select the MINIMUM number of units for all Elective Units. If Elective Units have more than one group, this should apply for EVERY group as well as ALL Elective groups. -Mapping/Notes/Date - section should be able to be duplicated (see Example3 & Example4 images) Further examples can be given upon request.
