Since you have a client profile at the moment, you'll need to create a freelancer profile in order to offer your services on Upwork and bid on jobs. Note that the preferences you mentioned will not prevent a freelancer who's not meeting these to submit a proposals and have their proposal displayed to client on the same list as other proposals.
We strongly advise freelancers to only bid on jobs for which they have the required skill set and experience to complete on time and in line with the client's requirements.
Join Upwork's social team on Twitter on October 28th at 10:30AM PT for a live Twitter chat. We'll be leading a discussion of best practices for profiles covering everything from photos to Project Catalog.Learn More
