By all means, have it and do as much as you can yourself. That is how lots of businesses get going, one guy figures he can do it more cheaply himself, or can do a better job himself.
BTW, why would a customer expect to not pay for a lunch break, a coffee break and a 30% bonus for taxes off the top, as well as a percentage of the overhead costs such as knowing how to do what you want done, and for having accumulated a bunch of equipment and/or premises on which said equipment is situated and set up to do the work conveniently?
First you get good, then you get fast. Then grouchiness sets in.
