as JB mentioned, $1000 isnt going to cover it.
you will have over $400 in incidentals and PPE, over $300 in plywood, about $75-100 in hardware, over $600 in resin, about $300 in cloth, about $300 in misc other fiberglass supplies, about $250 in 2-part foam, then about $200 in gel
estimate about $3500-$5000 for the hull, transom, stringers, other structure and vinyl if you do the upholstery yourself. Then add about 6 months to 3 years of weekends. then you get to the motor work
