My $0.02....
First off, you'll need to know as much about this 'scrap steel' that you can find, including:
A. The LOWEST cost the current business is willing to accept for it.
B. If they're willing to 'ship it' overseas possibly.
Once you have that, do this:
1. Head over to triple "w" <dot> alibaba <dot> com
2. Click on the BUYERS tab.
3. In the search box, type in SCRAP STEEL
4. Go through the results and see if you can find a buyer for the type of scrap steel that is available.
5. If there's any good candidates, create an account <fast & easy> and then contact them and let them know that you've got what they need.
If you are able to find a potential buyer, keep the email to the point and just let them know that you saw their posting and that you might have exactly what they're looking for. Depending on where the potential buyer is located (USA, India, China, etc., etc,.) I would expect a response w/in about 2, maybe three days at the most.
That being said though, you might want to contact as many potential buyers as possible, in order to increase your chances of finding the right buyer.
Excess inventory management is much like affiliate marketing...you find what someone NEEDS/WANTS and give it to them!
Once you've found a buyer, simply negotiate the 'deal' so the business w/the scrap metal gets a fair price, the buyer gets the steel for whatever price they're willing to pay and you make a few $1,000+/- in the process!
Don't forget...someone's garbage is someone else's treasure!
Hope this helps?
