I believe it is some sort of powder substance that they coat surfaces with.

During audits, the IRS tends to look at the substance of an issue in addition to the form.  

Take the time that is necessary to develop the substance before you attempt printing cards.A poorly developed business concept shows in your card: no real business name, no "what I do" statement, no legal entity, no fax number, no company web site and just a random gmail address. - All that shows you are a rooky.Until you have established and developed all these things I would go with less is more and just do name, phone number and email.

is it in the groundwater or notMost people think leaky storage tanks from gas stations and such are really expensive to clean up, but in reality this type of substance can be relatively cheap (none of its cheap).

You need more than an idea -- you need an opportunity and you need to have a competitive advantage to make that opportunity successful.Your best bet is to find someone with experience who can bring that experience to the table in order to turn your idea into an opportunity, and then you can pitch the opportunity along with some substance (your partner's experience and track record).Of course, you're going to have to prove to a partner that you actually have something to bring to the table as well...he's likely not going to consider your idea to be very valuable in and of itself.

@Ray Harrell I believe those hazard substance inspections are required to be done by licensed engineers in Washington DC, but yeah, I am pretty certain that I have to dig deeper for better prices at least. 

The business model was to help the veteran get setup on VA benefits, SSA and provide services around mental health challenges, substance abuse , etc. and eventually placed into short/long-term housing.In all honesty I underestimated how hard this process was and the idea quickly imploded and I lost money.So I was curious what you were doing...

Ideally I would like for ALL of participants to walk away with something of substance but that seems to be somewhat of a challenge because of the diversity in the class.

>> A federal jury Friday awarded more than $100 million to 10 workers who claimed they were injured in 2007 when a toxic substance was released at BP <<I bet I know which posters released that 'toxic substance' !!!.....

In the meantime, read and study as much as you can about all aspects of this field.Any legitimate real estate transaction of any substance requires attorneys to review and create contracts and deeds etc, earnest deposit money, substantial due diligence money for appraisals, surveys, environmental assessments (phase1 etc) and inspections.
