Should not presume that they misspelled "freelancer".
Perhaps they want want to work for free as a lancer in a medieval show in which case "free lancer" would be the correct phrase.
However, if OP actually meant "freelancer", as in an independent contractor who offers their skills and services to others in exchange for fair compensation, then we would need to know what type skills and knowledge do you have to offer? Programming? Design? Fixing cranky servers?
I did a quick Google search and discovered that there are many websites which connect freelancers with potential clients.
Good luck to you.
