Hi!
Sorry, I missed this post earlier! There are tons of things you can do get sponsors or advertisers. For a website, Google Adwords is one of the quickest ways to get advertising on your site, but there's not a lot of money made until you're pretty well established with lots of traffic to click on the ads. Building traffic is a whole other thing. . .
You can also do your own advertising/sponsorship programs and you already have a great beginning target list: drug and other medical supply companies who call on doctors all the time! LOL--seems like everytime I'm at the doctor's, so is a medical rep. But, I really like free samples!
