What can you even build in just one hour?
With a little bit of planning, quite a lot.
Besides, my experience with clients tells me that there are at least a few people who are building bots which can be prototyped quickly, but they take a lot of time because they don't follow a structured process when it comes to learning and applying Dialogflow.
By utilizing the Dialogflow Prototype service, you can speed up the learning and the bot development process because I can help you avoid the common Dialogflow mistakes, which can sometimes cost you weeks of development effort.
How it works
1 Sign up (it is free and takes less than a minute) on my course website
2 Book the call below
4 You should spend about an hour going through the courses and create the flowchart for your chatbot
5 Make sure you send me the XMind flowchart for your bot at least 24 hours before our call, as well as a brief description of what you would like to build
6 During the call, we build the bot together
7 If you need to create a webhook, we will use Airtable. You can take a look at this tutorial and try and prepare the data in Airtable before the call.
8 No integrations. I can give you a quick explanation on how you can do the integration, but I cannot do the actual integration with for e.g. a website, or with FB Messenger etc. We will do all our work within the Dialogflow console, which has a simulator.
The Prototype Bot service even comes with a guarantee!
What if we cannot build the bot successfully inside the hour?
If we cannot build the bot within the stipulated time, I will enroll you for no extra cost into the Dialogflow Toolkit course bundle. (That is, for the amount you pay for the prototype bot service, you will also get the Dialogflow Toolkit course bundle).
And what if we do build the bot successfully in an hour?
On the other hand, if we build the bot successfully inside the 1 hour , you can then purchase the Dialogflow Toolkit for only $100 more. 
In other words, if the experiment fails, you get a $50 discount on the Dialogflow Toolkit, plus learnt a lot about how to build Dialogflow bots.
If the experiment succeeds, you have a working Dialogflow prototype bot, plus you get access to the Dialogflow Toolkit for only little more than what you would pay for the Toolkit bundle alone.
So from your perspective, it is a very low risk - especially if you are already considering purchasing the Dialogflow Toolkit bundle. If you are on a tight budget and you just want to explore if it is possible to build a Dialogflow chatbot for your use case, this will be a very quick and pretty inexpensive way to find out. You might have noticed that while I call it a 1-hour Dialogflow prototype service, we both have to spend more time than that on preparation. However, you can compare it with how long a typical project would take for you, and you will see that in terms of time spent, this is a really efficient process.  If it works, you agree to give me a testimonial for the 1 hour prototype consultation call before I give you access to the course bundle.
The PayPal payment link is not working
In some cases, I may be able to arrange for alternate payment options. Reply back to the student signup confirmation email you received when you signed up for my course website with more details about your issue.
What if I don't want just a prototype but want to build a full bot?
As a big believer in building quick MVPs (Minimum Viable Products), my suggestion would still be to try and build a prototype if only to see how far you can go with your existing idea, before committing to a bigger budget.
