As @donnovan86 has said, you need to work hard and offer exceptional service. As a web designer myself it is disappointing that you're showcasing templates and themes as your own work. Anyone can download and take screenshots of them, but you're giving the impression that you have designed these and state them to be 'custom builds'. This is also apparent on your portfolio. Any experienced eye can see this, and I suspect that this may be a contributing factor to you not getting any gigs.
Also look at your gig descriptions, be a bit more professional in how you speak. the first words I see are 'i'm gonna design'. Where have you gone????
Put your own work up and let the client decide if it's good enough. Using a template is not web design, it's data entry, and your gig should reflect that this is what you're doing. Do not give the impression that you're offering a bespoke site when you're clearly not. If all you're doing is changing words and photographs. drop your prices and reflect what you're doing in your gig. You may get more sales that way.
Above all, be honest in what you do. state what you do in your FAQs and don't set yourself up to fail
