I am Daren from China. I am a leader of small IT group and have 8+ years of experience in web and mobile app development. To be honest, we are currently looking for a trustworthy individual who can rent his Upwork accounts to us. I'm not sure if you know, but Chinese are banned from joining all social sites and job sites like Upwork. So, we have been working with a foreign customer, using his account and computer, and paying him 20% of the profits or a certain fixed amount. However, a few days ago, a customer's Upwork account was closed due to a team member's mistake. That's why we're looking for people to work closely with us and rent out their accounts and computers. If you partner with us, we will pay you at least 20% of the money you earn on Upwork. If you are concerned about security and payment issues, rest assured. First of all, we will only use your computer for bidding and communicating with customers. And customers will pay us through your Upwork account, so you manage all payments. You can keep 20% of Upwork profits for yourself and send the rest to us. If this makes sense to you and is possible, I look forward to further discussion. skype: live:.cid.9afebbd1559b7552 whatsapp: +34 (690) 985-315 Thank you.
