TradingView Indicator Completion Using Pine Script

I'm looking for an experienced Pine Script v6 developer to build a custom TradingView indicator from scratch.

The indicator implements the TTrades Fractal Model (TTFM), an ICT/Smart Money Concepts trading strategy. I have the full strategy logic already documented in detail (a written spec covering swing point detection, Change in State of Delivery, daily equilibrium levels, point-of-interest hierarchy, fractal candle roles, and timeframe alignment rules), plus a settings/feature checklist based on a specific reference indicator whose look and functionality I want to match.

Core features needed:
- Fractal, multi-timeframe swing model with a fixed higher-timeframe look-back for detecting relevant swing highs/lows
- Change in State of Delivery (CISD) detection tied to important levels
- A fixed daily equilibrium (50% of previous day's range) rendered cleanly per session
- An HTF Candles side panel showing higher-timeframe candles next to the live chart
- Visual overlays: sweep lines, bullish/bearish CISD lines, a "T-Spot" zone, and candle-role labels
- Standard Deviation projections and Formation Liquidity target levels
- SMT Divergence between correlated instruments
- An info table summarizing bias, timeframe alignment, and time to candle close

I'd like this built incrementally, one module at a time, with a quick check-in and validation after each stage before moving to the next — given the likely size of the final script (800-1500+ lines), I want to avoid debugging a huge block of code all at once.

I'll share the full written specification and the reference indicator's settings manual once we're in touch. Could you let me know your experience with ICT/SMC-style or fractal multi-timeframe indicators in Pine Script, whether you're comfortable working in stages like this, and your estimated timeline/rate?
