I am an experienced writer/translator (Dutch-English) of software manuals. I have written productsheets for networking solutions and have designed software (functional design) myself.
I estimate that it will take me about three hours per page, for a maximum of 15 pages. That means 45 hours, hourly rate 43 GBP = 1935 GBP. Another 5 hours for checks, conferencing by WebEx, etc.
Total: 50 hours, 2150 GBP.
This bid is for the manual only, since the other work is not specified enough for me to give you an estimate.
I would like to be able to complete the project before July 23, because that is when my holiday starts (although I am willing to finish the project during my holiday).
