Website with forms displaying API data

Objective: create web portal for customers to sign-up to and view hidden content once signed up and paid. Looking for someone to create - Wordpress website (Theme already purchased, so can use existing theme) - Integrate a plugin in order to create client portal to display data based on customer sign-up and payment (something like - Pull back data from around 6 API sources and display in tables on website. API's will produce JSON format. I have already tested a few of them with WPDatatables and they work fine. One or two of them will need to be customised as the JSON format is not in correct array format for WPDatatables. - A few customer filters to be created. Ie. filter based on comparing fields from different API data from different providers. Maybe around 10 custom filters needed to be displayed in table. - No need for Logo to be created, I can do that. - Website will have around 8 - 10 pages, most viewable based on customer sign-up with username and password and payment. Example site with similar functionality is www.cryptostat.org. They pull data back from 3 API sources and display in a table. I have already tested this myself in 15 minutes on a test wordpress site and I am not a designer or developer, but I need some slight customisations and for the tables and site to be designed nicely.
