Debug Woocommerce website

Hello, I have a website that I was fully inexperienced in building and I should not have built it in wordpress. Either way, I have just a couple bugs that need to be ironed out, and I would like a quote of a fixed amount to work with me for a couple hours (because I know how it works and can guide you) to fix these. Bugs: - I used WP All Import plugin to import stock levels & prices & sync users from a csv into the WP db (the csv is updated by the company's main database) - all using cron jobs. When a stock or user import occurs, the prices get wiped - I used "Ignite_woo_tiered_pricing" plugin to generate 10 custom user roles (it also generated 10 postmeta fields for products that are custom prices). This allows for a user to be given a user role, and based on this User role, they get a given pricelist. When the user import executes, two of the user roles are not updated, but the other 7 are. So we need to spot the difference and fix the customer import. - I applied an SSL certificate: the result of this is that when in https, if you click dashboard or wp-admin, you get a 404. I could do with some help from someone experienced with wordpress. You will have lots of appreciation if you can fix my problems! Thank you very much
