In the online era a good cover letter is more important than ever. I've had a successful gig writing LinkedIn bio's for many professionals on Fiverr (see link below) and now offer to write your cover letter.
This letter can be used when applying for a new job, as a general 'hello' letter to a company you like, and even as an application to graduate positions and roles.
With this gig I'll write a cover letter for you that'll be tailored to your needs. All you need do is order my gig, send your CV and some info about the position - and any other info you may wish to - and I'll send back a cover letter ready to use right away.
