Hello Karan,

This is a really great question that I think I'm qualified to answer. I've been working professionally with SolidWorks for just over 10 years at my day job, but freelancing for more than 15 years. The funny thing is that I never actually intended to freelance, or actively sought out work. What I've come to realize is that I was unintentionally marketing my skills through sharing my work and creating design content with my particular interests (firearms), and people began to start seeking me out for their own projects.

Since you are intentionally looking for work, what I can offer you for advice is this:
1) Use your GrabCAD account to showcase real work. Right now, you have a lot of exercise models of abstract academic shapes that we've all done in school. Get rid of those, and start putting up some real-world functional designs.
2) If there is a certain type of design work/product you'd like to specialize on, make sure you are conveying that through the work you share, as well as specifically mentioning it in your profile.
3) Expand your audience. I started out sharing renderings of my work on DeviantArt, firearms forums, and general social media. Then I eventually created a GrabCAD account, Youtube channel, and LinkedIn. People have found me through all of these places. This took years to do, as I wasn't actually looking for side work. It just happened.
4) Since you are looking for work now, and not in a few years, you're going to have to be aggressive about reaching out. Find potential clients on here by looking at profiles with things that you are interested in and send a message, seeing if there is anything you can assist on. Expand your search off of this platform, looking for CAD gigs abroad. Make some sample work that you can share for free so that people can judge your skill before considering you for a job.
5) Always answer any inquiries and correspondence, no matter how trivial or uninteresting it seems. Word of mouth is a powerful thing. If you are short and disrespectful, or outright ignore people, they will tell others. If you are polite and respectful, even when you have to turn someone away, they will also tell others.

I'm sure there is more I could offer, but I'll leave you with this for your consideration. Good luck!
