I need some solid advice on how to get clients…
I guess the first thing to do would be to figure out the business need you fill for clients? They need to know WHY they need you. Always a good place to start.
Cold calling, networking, direct mail, referrals from existing clients, bidding on job sites like Freelancer, oDesk and Elance.
Lots of options - just depends where in the world you are, what services you offer, and who you are trying to go after. For example, if you’re a 1-person company, you’re unlikely to score 6-figure jobs for multi-national companies.
The Web Design Business Kit has tons of great content on how to write proposals, pitch clients, and is filled with useful case studies. Start with some of the tactics described in there.
