10. Architectural/Farm Layout Designer: A professional who can draw up plans for the farm, including the layout of fields, roads, sheds, and homes.

Caution Note: A local, inexperienced designer may propose an unrealistic plan that doesn't account for the land's actual topography or drainage. They may also suggest expensive building materials that are not locally available, driving up your costs.

11. Brick/Stone Supplier: Vendors who supply bricks, natural stones, or laterite blocks for all construction.

Caution Note: The supplier may deliver a lower-grade material than what you ordered, mix good quality with bad quality bricks, or deliver a shorter count than you paid for. Count every brick or stone and check for a consistent color, size, and quality.

12. Sand Supplier: A vendor for coarse and fine sand for mortar and concrete.

Caution Note: Sand is often sold with a high percentage of silt or clay mixed in to increase its weight. This will weaken your concrete and mortar. Be prepared to ask for a sample and check for cleanliness before delivery.

13. Grit/Aggregate Supplier: A vendor who supplies different sizes of stone aggregate for concrete foundations and flooring.

Caution Note: The vendor may supply smaller, lower-quality grit or a different size than you ordered. This will compromise the strength of your concrete. Ensure you specify the exact size you need and inspect the delivery closely.

14. Cement Retailer: Local shops that supply bags of cement from various brands.

Caution Note: Retailers may sell you old, expired cement that has lost its binding strength. They may also provide a lower number of bags than you paid for. Check the manufacturing date on every bag and physically count them upon arrival.

15. Steel Bar (Rebar) Supplier: A vendor who supplies steel bars for the reinforcement of concrete structures.

Caution Note: The supplier may provide steel of a lower grade or a thinner diameter than specified, which can compromise the structural integrity of your buildings. Always use a vernier caliper to measure the diameter and ask for the grade certificate.

16. Mason/Mistri (Skilled Labor): Individual or teams of skilled masons who work on a per-day or per-project basis to build foundations, walls, and sheds.

Caution Note: Masons may take advantage of your lack of knowledge by working slowly to extend their days or by doing low-quality work. They may also use more materials than necessary to benefit the material supplier. Get a project-based contract with clear milestones, not a daily wage agreement.

17. Unskilled Labor Contractor: An agency that supplies daily-wage laborers for digging foundations, mixing concrete, and other heavy lifting tasks.

Caution Note: The contractor may inflate the number of laborers they claim to have sent or may send fewer and less efficient workers. Always do a headcount at the start and end of the day. Also keep record of outputs on daily basis.
