You haven't posted the IP information so can't check that, but from a quick look at the advert, which I imagine is Copy & Paste, here are my observations if they help.
Harvey Business Associates LTD isn't listed as a company at Companies House, and there is nothing similar enough to be a error.
Harvey Business Associates LTD doesn't have a web presence that you would expect.
The wage itself seems far below the national average for Account Managers. After tax, even full time, your take home pay would be £17k p/a
Some of the syntax in the advert seems wrong and there is an overuse of Capital Letters, in the wrong places.
It's up to you, you have to make your own choices, just be aware of what you are sending.
