No, there is no way that is quick and inexpensive. Patents are presumed valid and the least difficult way to try to knock one down is an ex parte reexamination. Anyone can file a request based on submitting published documents and an explanation as to how they apply to which claims, and $6000. The patent office gets 3 months to decide if there is a "significant new question of patentablity". If not you get your $6000 back. If so, they proceed to examine it again, but with "special dispatch". At the end a reexamination certificate is issued that might say everything is fine, some claims are changed, some or all claims are gone. The requestor does not get to participate after sending it in.
No lawyer is technically required. You could draw it up yourself, or you can use a registered practitioner. That includes patent attorneys and patent agents. If one were actually spending $6000 in USPTO fees, another few thousand to get it done professionally seems wise.
