Programmer / Browser Script Designer Needed

I sell mattresses to customers in a physical retail store located in the USA. Many of these customers cannot afford to purchase the product without a loan. I work with 5 different companies that provide loans and will eventually be working with 7 or more companies. I need to work with so many companies because each loan company may not approve the customer for a loan, or they may approve the customer for too small of a loan.

So, the problem I am experiencing now is that I'm needing to fill out 5 different applications which is incredibly time consuming for both me and the customer. To solve the problem, I want to enter the customer's information in one spot (Excel or Google Sheets for example) and then have a program or a code open up the finance applications for the various 5 companies and copy and paste the customers information into the web form very quickly and rapidly by macro or code.

This is a one time project to get started and then follow-up work will be assigned on an as-needed basis. Salary is negotiable.
