I help small companies and startups market their services.

First step is to define your target market. All big companies will have PR firms as their retainers. So talk to PR firms.

Host some of your work/ templates on your web site as samples. You can even sell them from there.

Start talking more about UX and write articles and case studies about the same. Provide free advise in these articles and tips for doing the same. Remember that these tips are useless unless I am skilled enough to implement so you are not giving away any IP.

Big companies wont hire freelancers usually. So figure out who is the channel and work through them.

Please feel free to call me if you wish to discuss the same.
Best regards,
Sridhar
