I understand the amount of scepticism, as there are a lot of fake freelancers around. However, I've seen that this also affects a lot of legit freelancers, people are being declined for having fake examples, even though the example is theirs.
This is quite worrying for me, I am a new user to oDesk, but have degrees within my field, and have a few relatively polished portfolio pieces.
How can I make sure the client doesn't believe I'm lying?
Could someone take a look and give some suggestions?
Due to these messed up boards, I can't see your profile, but I'd say if you have really good work and some less impressive work - dump the less impressive. Quality over quantity. As well as looking consistent. As I mentioned before - polished work is NOT what makes me suspicious - polished work mixed with banner ads made with Comic Sans makes me suspicious
Your rate isn't super high, but it's not in the cheap range. Clients with no taste won't know the difference between your portfolio and anyone else's, so they'll be going for people at $5/hr anyhow. Sell yourself on your skills - to clients who recognize the difference.
I get a lot of invitations to interview and even job offers without even interviewing all because of my portfolio. I've put a lot of effort into keeping it up to date, providing detailed information in it and presenting it in an eyecatching way.
