I am a part-time programmer contractor and usually I do everything myself, including meeting clients, writing the proposal, programming, the whole 9 yards. I would like to hire someone to split the non-programming tasks so I can focus purely on programming (with project management).
How much should I give my new secretary as a percentage of a project's total cost? Usually my projects are pretty small from a few hundreds to the low thousands.
Their responsibilities will be mostly 2 parts: to acquire projects by doing marketing, and to meet clients when necessary.
EDIT: I was originally thinking 20%, too much/too little? Please let me know.
EDIT 2: I currently work by myself and do not hire anyone.
