Hmmm…I fail to see the logic behind this statement. Pricing has no effect on ability to perform the work. I’ve done similar projects for free many times for friends in the past all of which were successful.
If this made sense, no one could ever start doing independent contractor work no matter how well they could perform the work. >
If you don’t know what to charge by the hour, or how many hours it takes to do something, then no, you can’t do the work unless your business plan involves being a starving artist or going out of business in three weeks (unless you have a trust fund), which is totally useless to the client you can no longer service due to lack of funding.
