First Rodeo on bidding a lawn maintenance job

Hopefully Im posting in the right area. My son is excellent at mowing and landscaping yards. He has his first client as of yesterday. The job will mainly be cleaning up an uncared for property (about 3/4 acre). He will be doing some extensive weeding, trimming bushes, mulching, and possibly mowing. My question is we are at a loss of how to bid the job. Never done this before. Yard has alot of weeds and bushes that need trimming. We wil supply the equipment. Client will supply the mulch. Let me know if more specific information is needed. Yard is located in Iowa. Thanks
