You will have to seek out the opportunities and bid on projects just like the rest of us, but there is a little advice that might help you along the way.
You are new to Guru, and your profile is not at all complete. You really need to put some time into that, as employers will use the data you provide along with your proposal/bid to determine if you are someone who is capable and qualified to assist them with their SEO work. You use your profile to "sell" your skills. It should be the best that you can make it.
If you are having trouble putting your profile together, put a little time into researching what others on Guru have done, but DON'T copy them. Your profile is about YOU and your abilities, so make sure that it's unique and highlights why you are the person they need to hire.
You can find all sorts of helpful tips about profiles, bidding, writing proposals, etc in the freelancer help section, as well as right here in the Answers section. You can search a number of topics here because most freelancers experience the same issues when they are new.
