I think product knowledge is an important part of any sale, and selling what you know best could be the best thing to do.
Sounds to me like you have the right attitude, crawling before you try sprinting, and gaining some valuable learning experience along the way.
The Auction-Source venture certainly is an interesting one, and it's something I would dearly love to see get a good foot hold, but for now it is taking a back seat due to other more pressing ventures demanding much of my time.
Hopefully some time next year I can progress that a little further, but good luck with your sales, and congrats on your daughters upcoming wedding : )
