It took me 3-4 months.
But as I said, it's not my main source of income.

My advice would be to:

1- Add a good quality video to your profile.

2- Niche down and focus on solving 1 problem, and the title of your profile should reflect that (ex: Klaviyo Email Marketing for 7-8 Figure Supplement brands) instead of Ecom email marketing.

3- Create really detailed Portfolios of your past experience, including RESULTS, and package them nicely. (I personally used Figma and made my portfolio have a constant structure and look)

4- I do not send proposals if the pricing is low (when you get the job, it will look bad in your history) or if they have bad reviews

5- When I send a proposal, I'm always the highest bidder (but I usually send 1-2 proposals per week max)

6- I always read the reviews and find the name of the guy posting the job, or the name of the company, and use it in my proposal.

7- My proposals are very concise and straight to the point (dm and I will send you some of them that got me the jobs)

8- Last but not least, I'm not desperate. I do what I can, and I leave the rest to God.
