Now it was time to get down to business. Randy bought 500 business cards, a telephone answering machine, and a full-size van. Quick Delivery Service, Inc., had officially begun. As the first and only employee, Randy remembers his humble beginnings. He did his first delivery for $6.00 for his first client, Englewood Electric in Hoffman Estates. "The whole first week netted me $18.00", Randy says. His second account was a company called Allstate Press.

By the end of his first year, Randy was able to purchase another van, but that was very short-lived. The van was sold shortly thereafter because of maintenance problems, and the first Independent Contractor signed on after almost a year in business. The work consisted mainly of local small-package deliveries.

In the beginning Randy conducted his business like many small companies, right out of his house. Within the next few years, Randy hired more drivers and obtained Quick's first office space behind the old Snuggery Restaurant in Schaumburg. The condo was small, 800 sq ft, but large enough to conduct business at that stage. As the company grew and ran out of space, the condo next door became available, adding another 1,000 sq ft. With a total of 1800 sq ft now available, the business grew faster than ever, and in 1986 Randall Seiler DBA Quick Delivery Service became Quick Delivery Service, Inc.

In 1988 the next Authority was obtained. Randy purchased a company called RB Delivery, which came with a General Commodity authority and a radius scope of 160 miles, with the ability to use trucks. A truck also came with the purchase, and Quick Trucking started up.

In 1990 Quick changed over from Independent Contractors to employees. Quick also got their first 2 computers, the first being a Commodore 64 (with a color monitor!) and the second being an IBM XT Turbo clone.

In 1996 Randy sold the 2 condos and Quick moved into a larger 5000 sq ft building at the current address of 632 Pratt Ave N in Schaumburg. The move-in was accomplished over one very busy weekend in spring, with all the computer and office equipment moved and installed by the devoted employees. The new facility had an overhead door and a truck dock, and room to grow. In 2018 Randy acquired the adjacent unit for a total of 10,000 sq. ft. of office and warehouse space.

1999 saw the beginning of a Rockford (Loves Park) office, also in a building with an overhead door and a truck dock. The Rockford office offers all the same services as the Schaumburg office. It started as a 2-man office and has grown to employ 6 now.
