Aquaculture System Designer Needed (Tilapia + Guapote) – Solar Aeration, Water Flow, Tank Layout

I am developing a freshwater aquaculture project in Bagaces, Guanacaste, Costa Rica. The farm will raise tilapia and blue guapote in a multi‑tank system with solar‑powered aeration and proper water‑flow management. I am seeking an experienced consultant or engineering team to help design the system and provide technical guidance. I already have a local supplier who offers a turnkey package (tanks + solar + aeration + consulting), but I want to compare options, validate the design, and possibly build parts of the system independently to reduce cost. I am looking for experts in one or more of the following areas: • Aquaculture system design (tilapia, guapote, or similar freshwater species) • Tank layout planning (4 tanks, ~1500 fish each) • Solar‑powered aeration systems • Water flow, filtration, and oxygenation engineering • RAS (Recirculating Aquaculture Systems) • CAD drawings / technical schematics • Feeding schedules, stocking density, harvest planning • General aquaculture consulting Project Goals: 1. Create a complete technical design for a 4‑tank freshwater fish system. 2. Design a solar + battery aeration setup that ensures stable oxygen levels. 3. Provide water‑flow and filtration recommendations. 4. Compare the cost of a DIY system vs. a turnkey system offered locally. 5. Provide risk analysis and best practices for tilapia + guapote farming. 6. Deliver CAD drawings, diagrams, or schematics for construction. 7. Offer ongoing consulting as needed. Deliverables: • System layout (top‑view + side‑view) • Solar aeration design (panels, batteries, controllers, pumps) • Water‑flow and filtration plan • Stocking density + feeding schedule • Harvest cycle plan • Cost comparison (DIY vs turnkey) • Optional: Bill of materials (BOM) Ideal Freelancer: • Experience with aquaculture engineering • Knowledge of tilapia or similar freshwater species • Understanding of solar systems • Ability to produce clear diagrams and technical plans • Strong communication skills • Experience working with rural or off‑grid systems is a plus Please include in your proposal: • Your experience with aquaculture or solar systems • Examples of past work (photos, diagrams, CAD files, etc.) • Estimated timeline • Estimated cost • Any initial recommendations This project is part of a larger farm development initiative in Costa Rica, and long‑term collaboration is possible. I look forward to working with a knowledgeable and reliable professional. --- Next Steps Here are the next strategic moves you can take: • Post this on Upwork • Find 3–5 candidates • Prepare interview questions • Compare José’s offer vs Upwork proposals --- If you want, I can also create: • a Spanish version • a more technical version • a shorter version • a version focused only on solar • a version focused only on aquaculture consulting Just tell me what direction you want to refine.Absolutely, Jaime — let’s build you a professional Upwork job post that attracts the right team: aquaculture designers, solar engineers, water‑system specialists, and consultants who can help you compare José’s offer, reduce costs, and design a world‑class tilapia + guapote system. Below is a complete, ready‑to‑publish Upwork post written in clear, professional English (because Upwork freelancers respond better to English). It positions you as a serious client with a real project, and it invites experts to propose solutions. --- Upwork Job Post: Tilapia & Guapote Aquaculture System Design (Solar + Water + Tank Layout) Title: Aquaculture System Designer Needed (Tilapia + Guapote) – Solar Aeration, Water Flow, Tank Layout Description: I am developing a freshwater aquaculture project in Bagaces, Guanacaste, Costa Rica.
