Connect the required functionality via API and configure voiceflow.com

I am looking for someone who can set up voiceflow.com for me and connect the necessary functionality via API.

Currently, I need to create a basic version, and then add additional features. 

Please write how much time you think is needed for the basic version, when you can start, and the price. 

You can suggest other methods if you know a faster and simpler option than creating this in voiceflow.

Project Description: A space where you can express yourself and receive support from an empathetic AI assistant. Record voice messages, and the assistant will provide useful insights and support. Everything is simple and confidential.

Project Tasks:

Set up voiceflow.com according to the specified scheme and connect services via API. 

The main functionality is recording voice messages, analyzing them through the Claude API, and providing an empathetic response to the user.

Work Plan:

1. Create and set up the project in Voiceflow

   • Basic greeting
   • Audio recording setup
   • Conversation prompts

2. API service integration

   • Connecting audio conversion
   • Connecting Claude
   • Basic prompts

3. Testing and launch

   • Check recording
   • Check responses
   • Fix bugs

After launching the basic version, the following can be added:

• Export of dialogue history.
• Encryption of exported dialogue.
• Intro before the session starts with topic selection.
• A short survey for the user about the quality of the session.
• Scheduling the next sessions with addition to the calendar.
• Add Lithuanian and English languages.
• Analysis of how long the user was present, counting how many resources were used in the session.
• Login function with code input. Only the code, without a name.

Detailed plan and scheme:

1. Start page

• Title: “Let’s start a conversation”.

• Short prompts: “Speak freely, tell what worries you”.

• Button “Start recording”.

2. Audio recording

• Maximum duration (for example, 15 min).

• Button “Stop recording” or “Done”.

3. Voice to text conversion

• Send audio to Speech-to-Text service (for example, Google Cloud, Whisper API, or another).

• Receive text, display it to the user.

• Delete (or not save) audio for confidentiality after user confirmation of the text.

4. Sending text to Claude API

• Built-in API call: text + short instruction on the tone of the message or what help is needed.

• Receive response.

5. Displaying the response

• Show the message from Claude.

• Offer: “Repeat recording” or “Finish”.

6. Repeat cycle or finish

• If “Repeat” — return to the recording blocks (step 2).

• If “Finish” — a short “Thank you for the conversation!” and end the session.

7. Deleting information

• Press the delete button to remove all information and show that it has been deleted. 

8. Minimal design

• Simple buttons, clear short instructions in Ukrainian.

• No additional fields or complex forms.
