Landscape design: Hardscaping our front yard+additional parking

Hi, We are looking to reduce the amount of lawn in our front yard and are looking for some help with regard to design. Our budget for the whole project, including design is limited to $5000. We would like to : -reduce the amount of lawn we have to the bare minimum -add additional parking (we currently have a carport that leads up to a one car garage. During winter, we have to juggle our vehicles based on who is leaving first) -we like modern contemporary design with few plants, but would also like it to be as environmentally friendly as possible (don't want to create a concrete jungle that supports no insect life) -we would like recommendations on possible options for materials to be used for the driveway/parking area (poured concrete, bricks, gravel etc. based on the best option in terms of being low cost + minimal upkeep.) -we have children who have severe skin problems don't want to any chemicals for upkeep AND I hate weeding, so if you have any ideas for minimizing weeding, like really narrow strips of soil, just wide enough for a row of yucca/grass/lavender etc, please offer such suggestions -an actionable plan that includes all technical information such as grading, measurements etc as we have no knowledge of these things Thanks for your interest.
