Located in Idaho, Linguaplex provide online language tutoring and proofreading, editing, CV, business and presentation services.
Not just restricted to English, Linguaplex also seek Spanish plus other linguists to take on. The pay per 25 or 50 minute class is $11.20 or $18.20 respectively. Two 25 minute classes back to back however will earn you $22. A 250 word document to correct pockets you $5, there’s proofreading and additional services to help top up the kitty.
The rub of the green with Linguaplex is that they don’t require you to have a degree, just a certificate with previous online experience.
You must be from a native English speaking country. They pay via Stripe (not Skype) every few days apparently so were you to complete some classes on the Monday you should receive payment that same week.
