Go online, use Callmart.

Create a Callmart listing once you've downloaded the app on your phone. Your listing can provide services for anyone you wish - e.g. giving advice to aspiring instrumentation engineers, or a listing for any client to contact you online. This is the start to your own online job!

There are three crucial parts to your listing: title, description and photo. All three of these should represent who you are and be able to communicate the general content of your listing. Pay extra attention to these three components and you'll notice an increase in the number of Callmart users calling you for your knowledge.

Of course, you have the freedom to go back and edit the cost per minute of your listing any time you wish. When you're choosing the cost for your listing, you can go with the convenient option of choosing from one of the suggested amounts displayed on the screen, or simply create your own cost per minute as you desire.

Pros for Instrumentation Engineers

A large majority of instrumentation engineers don't have time to promote their listing, so we do it for you. Callmart's share listing option gives your listing a specific URL that can be shared everywhere online by tapping a few buttons on the app. This is a big timesaver, so use it to promote your listing on sites like LinkedIn and any site in relation to your company (i.e. personal page) - this will bring in more clients to your business!

Callmart supports transactions in 135 currencies. The app is also available in 6 languages - English, French, German, Japanese, Korean and Spanish. The built-in global marketplace lets you offer your knowledge and experience to billions of people throughout the world. Start changing the world for the better!

Worried about late payments and/or not getting paid for your services? Callmart's automatic per minute charging system eliminates all these troubles. Our system is completely safe and guarantees you receive your money on the app as soon as you've finished a call between you and your buyer!

The Ideal Online Job.

The ideal online job is possible for any instrumentation engineer looking to earn money using just their knowledge and free time. Publishing your listing on the global marketplace will make it visible to any buyer browsing Callmart, but if you only want to send your listing to someone you know, you can toggle it to private.

All our platform charges is a 3% fee, which goes towards continuing and improving our services for all of our users. We use a third-party online payment processing service, Stripe, that charges a small fee as well.

Use Callmart whenever you feel like it, or whenever you have free time - even if it's just a few minutes! All you've got to do is talk, get paid, then transfer your earnings to your bank account!

Callmart is a global C2C marketplace app that connects instrumentation engineers with client through charged phone communications.
