First of all … This business is not for everyone. … It costs a lot to setup … But the good news is that, the profit potentials is very huge & competition is very low. … And most of all, you are selling what really helps to better other peoples lifes.

What you need to do is,.. Get a website designed with a shopping cart plugin enabled in it for you.
Find manufacturers & distributors of disability items like wheelchairs, walking canes, bath-shower chairs, walkers, jel gloves, scooters, powerchairs and so on. .. The list goes on and on.

It is just like starting any other online business … I dont know much about this type of products .. but I am very sure that, it is another great business idea that you can consider learning more about.

Marketing the website: Advertise your products in hospitals & clinics, use the yellowpages to gain more customers, try google adwords for more web visitors AND advertise in disability chat forums.

Another way to grow a business like this, would be through, adding your own online forum in a different section of the site… this brings more people to your website and allows your customers to discuss the products and exchange ideas on which products work best for them.

Researching this business opportunity, will be a very good start.
