Excel/VBA Macro Upgrade for excel Inventory Program

I'm seeking an expert excel/vba programmer. I'm using an existing vba macro excel program that needs to be upgraded. It was created to automate the process of building a single inventory list from multiple vendors feeds. The website is now using the Shopify platform and requires data to be imported into different column names and for more columns added. Summary of work required: 1. Need to change the import process to a single form, where feed can be added, vendor profile selected, map file column names to names in the program, save profile and import feed. 2. Adjust Export functionality to use similar template with different columns for different export options. 3. Data in compiled list needs to be read only unless enabled for in-line editing 4. Need a button to be able to add a single line to the sheet if needed (this will add a new line with all formulas/repetitive data columns already completed) 5. Column N thru AF is currently using split and some other formulas to manipulate the vendor categories Iine column AF the vendor categories are renamed to AGB category names (located in sheet CAT Reconcile sheet) This functionality needs to be programmed in to allow categories from vendors to be automatically renamed and added to column AF Also - Build Cat Reconcile feature - ability to be able to see existing categories and their assigned AGB alternative + be able to add new ones NEW FEATURE 6.
