Quality check and fixes on complex data entry woocommerce 2500 items (READ FIRST)

Hi i need someone to do a quality check on about 2500 products on website. MAKE SURE TO READY WHOLE PROJECT INCLUDING ATTACHMENT BEFORE BIDDING. THIS IS NOT SIMPLE DATA ENTRY IT INVOLVES MANY OPTIONS, VARIABLE PRODUCTS, DROP DOWNS, COLOR OPTIONS, AT LEAST 20 DATA ENTRY SPOTS PER PRODUCT. DO NOT CONTACT THROUGH THE SITE. MAKE SURE ONLY BID IF YOU HAVE TIME FOR THIS JOB IT WILL PROBABLY TAKE AT LEAST 4 WEEKS. I DONT HAVE TIME TO WASTE. MAX budget is $400 so do not come with anything higher, your just wasting your time. [login to view URL] Your job will be to make sure all products are entered correcty, include all data, correct description, fields, weights, colors, drop down boxes etc. Previous person made a lot of careless mistakes by duplicating items and only changing certain parts. Issues like no weights, options belong to other products, missing the option to pick one or two sides, colors or item may only have 1 side but they put two. They also left conflicting details about other products in the description and categories. Their problem was it was a long task and they kept changing teams so there was no quality check and there is a lot of learning involved. Product options are very detailed. Product catalog can be found here they they pulled data from [login to view URL] (this is only for basic idea, i have to change one of the catalogs and there is an excel spread sheet that i have to send for some items. The two catalogs you can pull from an excel project you have to just double check the data and on all just update the shipping information as i created a new plugin as shipping was wrong. The project is divided into 2 sections: paper printing (catalog based) promotional products like pens bag etc. (excel based) Project contains about 2500 items that you will have to go over (i think there is probably a 20-30% error rate). Most of the work is done, it is just verifying and editing what is missing and add options where needed but settings are very detailed on the printing catalog. I will go over some basic training so you understand how things should look. I need someone who can decicate a few weeks to 1 month to this project unless you think you can do it fast. But some steps are detailed. Backend view of some items: [login to view URL] [login to view URL] [login to view URL] Attached sample of the instructional guide. The printing is the most complex part about 800 with probably the most errors. The first product if not entered may take about 10-15 minutes but then its duplicate and just change prices, titles and size.
