Okay - reality check here I think! (sorry)
Google doesn't like NEW websites, it's very difficult to get even a 1/2 decent ranking for at least 12 months. PLUS your target keywords must be one of the most competative on the net
The key is to add your website to high PR directories, my honest advice is DO NOT pay for directory inclusion, no matter what the PR of the directory - but that is upto you.
Forum links are fine - but not the best way of getting good solid links, you need 1000+ inbound links to get a good Google PR and probably even more for a web designer (this is a rough guess). I've currently got about 1300 inbound links and I still don't figure anywhere in the top 50 rankings for UK hosting companies
