The most important thing you need to know about a custom essay writing service is that they should have a good reputation among the customers. Apart from that, consider the following points to tell if the agency is reliable
If they were reliable, they would not ask you to pay directly via bank account
You do not have to pay complete advance payments to reliable agencies. You can set milestones and pay as each milestone is completed. The other way is to pay the half amount upfront and release the rest after the completion of the work
They would love to show you their portfolio if they are reliable. They know what they are capable of so they offer good value to their customers.
Professional agencies hire writers after conducting interviews and certain tests. They will have writers with advanced level degrees who can easily create assignments in the given area. The writers should also be native English speakers. Do not work with someone who is an overseas writer because they may make grammatical and common spelling errors in the assignment
One thing about professional writers is that they are confident of their skills. They will not hesitate to offer revisions because they know you would like what they create. If a company is not comfortable in offering revisions then you should not work with them.
Essays that professionals write will be completely original. You can check the assignments with software on the internet and see if the paper is 100% unique. You will also have to check if they write custom essay from scratch
Professionals never delay your paper unless there is a change in requirements from your end. They will meet the deadline and deliver the assignment on the agreed date. You can check their previous work samples and the deadlines to see if they can write your paper in the given time. If you require this assignment on an urgent deadline, then you may have to pay higher than usual
A professional writing agency will not charge very expensive for writing your essay. Do not fall for cheap service providers because they may be low quality or spam. You need to find a reasonable writing agency or writer who has affordable rates.
