Custom Wordpress Work - Plugin coding adjustments, help with Import

I am on the final stages of a website launch and require assistance in a few technical details. I am an experienced Wordpress developer and just require some help on specific complicated functions. DO NOT CONTACT UNLESS YOU HAVE SPECIFIC EXPERIENCE USING THE ADVANCED CUSTOM FIELDS PLUGIN. Scope of work is as follows: 1) Adjustment of a Github plugin that integrates with the Advanced Custom Fields Plugin by Elliot Condon. The plugin provides the ability to add a Star Rating System as an ACF custom field. I need this module revised to work within an ACF Repeater Field 2) Adjustments to Really Simply CSV Importer to allow CSV Import into specific Advanced Custom Fields' Relationship fields to populate values by PostID. I have a large # of Posts to import with values for ACF Custom Fields. The Really Simple CSV Importer works 95% on its own - i just require tweaking and troubleshooting. 3) Various custom taxonomy changes and imports. 4) Adjustment of Wordpress native search to etiher be plugin based or hand coded to access specific categories in various search boxes.
