I have recently been offered some copywriting / copyediting / proofreading work. I have given them my prices for the three different services.
I have been asked to bill for my services for the first few pieces of work I have done for them, but going forward, they have mentioned putting me on a "retainer", which I am completely ignorant about. I assume it means paying me a fixed amount each week - but presumably with the expectation of x number of hours. How would this work? Would I need to renegotiate a payment per hour?
Additionally, do I need to set myself up as self-employed? Totally new at this (at the moment I am home with the little ones, albeit I do file a self-assessment tax return as I have a small income from a flat I rent out).
Any help/advice really gratefully appreciated.
