Step 1

Freelance, for anyone.

Open up the app and make a Callmart listing for your freelance job to begin. Your listing can be anything - for instance, to help chemical engineers around the world with industry tips, or helping others with any industry-related advice.

Due to the sheer amount of sellers on the marketplace, push the odds in your favor by taking time with making your title and description as short but informative as possible. For your description, you can do this by using bullet points, or a short summary of the important points of your service. Top it all off by including a photo that is of high quality (i.e. unpixelated).

Adjusting your fee per minute is always doable even after you've created your listing, so test the waters out! Start with one price, gauge the amount of calls you actually receive as opposed to your expectations, and then adjust your price based on that.

Step 2

Value for Chemical Engineers

Once you've created your listing, it's time to promote it to the rest of the world. It's really easy for designers to do thise with Callmart's share URL feature. Clicking 'share' after listing creation will provide you with a special URL for your listing that you can use to share anywhere. Use this to promote your listing on freelancing sites, and also your company site to make your listing easier to access for your clients.

Callmart provides you with new opportunities to interact with people from all around the world and make money from doing so! Our app has been translated in 5 very commonly spoken languages (Japanese, Korean, German, French and Spanish) and transaction support for over 100 currencies (135 to be precise!).
