This eliminates wasted time. You can type your search terms into the excellent search service on the site's front page and go straight to the information you want. QuickQuote is one of the most useful features of the site. QuickQuote puts buyers and sellers of products and services together. If you're a buyer, you choose the service you want, explain what you need, and wait for quotes from qualified sellers.
Sellers simply check out the business requests, and submit quotes to the buyers.
Unfortunately QuickQuote is available to US residents only. At first blush this might seem unfair, but I'm sure it cuts down on frivolous quotes. If you face a challenge, and none of the articles you find seems to address it, investigate the Discussions section of the site. At least one of these probably struck a chord with you. You can read the discussions without joining, but if you want to ask a question, or reply to someone else's question, you'll need to join.
