Tamarack,
I have done the job you are asking about. Unfortunately, there is no simple answer. It all depends on a few highly variable details. (1) Will you do it yourself or pay someone. If you do it yourself, do you already have the tools you need or do you have to buy them too? (2) What condition are your hulls presently in...do they need fiberglass/fairing work first? Or is she ready to paint as is? (3) What quality of job do you seek? Will you be painting with a top-of-the-line, 2-part polyurethane and epoxy primer (expensive but durable and beautiful) or something less expensive.
If you go with the two-part poly, the primer and paint alone will cost you a few hundred bucks. And, even starting with perfect hulls, the prep-time will be an entire days`work. This should start to give you a vague idea of some of the costs involved for a quality job. On the other hand, I know some fellas who have simply used cans of cheap spray-paint to arrive at a "paint job". This is not my choice, but it can satisfy the needs of some.
If you can provide several close up pictures of the conditions of your hull and what kind of job you are looking for, I may be able to give you a better idea of the "man-hours" involved as well as material costs.
Here are a few links to my most recent fixer-upper project (a 1977 Hobie 16). This job was what you would consider an all-out effort with all the best materials. The starting point was a very rough H16 - to put it mildly.
I recognize that not everyone wants to do the "spit and polish" approach to things. I do so simply because I enjoy it very much.
