Good day!
I am ready to create a Telegram bot according to your specifications (RU/EN, route calculation, automatic price calculation in €, "Accept → transfer to chat with manager", admin statistics/export).
Technologies: Python (python-telegram-bot) + Google Maps Distance Matrix API or OSM+OSRM; storing configs/rates and texts in JSON; deployment on Railway/Render.
Deadlines:
MVP (languages, route input, calculation of km+ETA+€ by formula, accept/reject buttons, notification to manager) — 3–5 days.
Full functionality (multi-stops, admin panel/statistics, CSV export, editing rate formula, error handling, GDPR feature for deletion) — 7–10 days.
… Support: 14 days bug fix after delivery.
Budget (EUR):
MVP: €450–650
Full version: €900–1300
(more precise after answers to the questions below)
I would like to clarify to get started:
What pricing scheme are we implementing: base_fee + €/km (+ €/min?) and different prices based on route types/time of day?
Which routing provider do you prefer: Google Maps (paid API billing) or OSM+OSRM (no billing from Google, but a separate hosting solution for routing is needed)?
Where do we redirect the client after "Accept": link to the manager, to a group, or do we create a "chat by button" (via link)?
Is a manual price override by the operator required before sending the offer?
Is a log in the database required (requests, prices, status "accepted/rejected") and admin roles?
Where are we hosting: Railway/Render/DigitalOcean? Is my deployment and domain/SSL setup needed?
Are limits/quotas on requests per user (anti-spam) required?
Is CRM integration needed now or do we leave a hook/export for future integration?
I am ready to start immediately after confirming the map provider and pricing formula.
