Online forms and services do not contemplate all that is necessary to produce custom, thorough, well-thought-out estate plans. That said, estate planning done well does not have to cost several thousands of dollars.
I generally charge $75 for intitial consults, which average a couple of hours. After an initial consult, there is usually not more than two or three plan options that make good sense, and one of the options usually stands out as the most viable/plausible. I can then quote the prospective client a reasonable flat fee for that agreed upon plan. That way, people know and understand on the front end (and before hiring me) exactly what their total cost/fee will be, and more particularly, what to expect in exchange for that fee.
