I don't need 3. The first and only thing that you should do is a Proof of Concept (POC) / market validation.
Only if it shows positive results, should you move on to the next stages (MVP, funding, founder's etc - depending what you already have/don't have).
You can read how to do the validation in one of my previous answers here: https://clarity.fm/questions/6423/how-do-you-do-market-research

Hi, It's interesting that you are trying to tap into more specific target customers through Airbnb while a lot of people are simply serving tourists.
Here are my recommendation:
- Make sure you know about your target customers - SME, corporations, etc? For what purpose would they use it? Their likely budget for this service? etc
- Create strategy of how to reach the target customers - cold calls, social media, digital media, ads, etc
- Make sure you have the product that they want - small and practical location or more luxurious? etc

I'm available if you have more questions.

Dear Sir I work with people who use airbnb my opinion is that if your income is higher than your usual competitors, look for someone who can make you a website
