SaaS developer to build an AI receptioni

Hello,
I am looking for an experienced Base44, no-code, or low-code SaaS developer to build an AI receptionist, WhatsApp chatbot, website chat, appointment booking, and CRM platform.
This product must be built as a real SaaS platform, not a simple internal app.
The platform should include:
AI receptionist for phone calls
WhatsApp AI chatbot
Website chat widget
Built-in CRM system
Sales pipeline
Lead management
Contact records
Call and chat history
Appointment booking
AI knowledge base
Human handoff
CRM integrations
Automation workflows
Stripe billing
Admin dashboard
Agency and white-label options
I also want the system to integrate with CRMs such as GoHighLevel, HubSpot, Zoho CRM, Pipedrive, Salesforce, Keap, Monday CRM, Airtable, and Google Sheets.
If full integrations are too much for the first version, I want clean placeholder integration screens, webhook options, and a plan for the next development phase.
Please let me know:
Can you build this in Base44?
Can you create the built-in CRM?
Can you add CRM integration options?
Can you build this as a subscription SaaS?
Can you include Stripe billing?
Can you create an admin dashboard?
Can you create an agency or white-label version?
What integrations do you recommend for the MVP?
How long will the MVP take?
What will the full project cost?
I need a clean, professional, scalable MVP that can be tested, sold, and improved over time.
