Where can I procure medical supplies on a small scale?

I have recently become involved with an organisation in Kibera, Nairobi which hopes to open a health clinic servicing their school and eventually the community within the slum. I am an Australian registered nurse, but based in Canada, and currently the only health professional involved with the organisation. The organisation is very small but a great initiative and one which I am committed to long term. At this stage although we have a dedicated building, we do not have the staffing or supplies to open the clinic on an ongoing basis. For the interim, we are planning to open the clinic for a couple of weeks at a time throughout next year until we are able to staff the clinic full time. I will be travelling to the clinic in November this year with the intention of establishing health records for the students and conducting a few workshops on issues surrounding HIV/AIDS, food & nutrition, sex education etc.

As this is a new project we are still trying to find a company that can supply various but basic cost effective pharmaceuticals and medical supplies for the clinic on a very small scale basis. Can anyone recommend suppliers or contacts, that may be able to assist us? Also, are you able to offer advice on the logistics of importing medical supplies into Kenya? I am also lead to believe we need to register the importation of such supplies with the Kenyan government?

Any advice anyone could give would be much appreciated. Many thanks,

Vanessa
