About this estimate

This is a budgetary estimate in Sri Lankan Rupees for a single landing page presenting Ecomech Engineering Lanka's identity, MEP capabilities and completed projects, with an enquiry form, built to stand up to scrutiny from hotel tender panels. Figures are ranges based on the scope discussed, and now include a small contingency for minor requests raised after development. A fixed itemised quotation follows once the discovery questionnaire is returned.

Custom quote
Per-page figures cover both design and development of a page reusing the established layout system. The three prototype concepts are a one-time design-direction exploration delivered with the primary landing page, and later pages reuse that direction. Pages needing new layouts or bespoke functionality are quoted separately, and pages added after signing are charged on the page base rate with a phase multiplier: Design x1.0, Development x1.4, late development or pre-launch x1.8.
How payment & changes work
What could change it
The estimate assumes you supply company text, project details and usable photographs of completed installations. Costs move upward if we write or restructure the copy, retouch or source site photography, build a filterable project database, add multilingual content, or if the enquiry form needs to feed a CRM, generate PDF capability statements, or handle document downloads for tender panels. The contingency covers only minor post-development adjustments. Anything beyond the agreed scope is quoted as a written change order before we build it.
Next step
Complete the short discovery questionnaire, including the industry questions below, and we will convert this into a fixed, itemised quotation with a delivery schedule. There is no upfront payment: after you approve one of the three design concepts we invoice 30%, with the remaining 70% due on delivery before final handover. Up to two revision rounds on the selected concept are included at design stage, refinements to the approved design during development are included, a 30-day defect warranty follows launch, and aftercare covers your first 5 change requests free, then LKR 6,000 per change request.
