You have a very small "niche" audience. I've heard of Thailand, but I've never heard of Pattaywa. I assume it is a city?
It is obvious from your blurb that English is not your first language. You need to have someone review this and clean it up for you. I suspect this applies to your book as well.
Someone who is planning to go to Thailand might well pay more than 2.99 for inside info on where to go, even unedited - but 9.99 would be a bit much, unless it was from a well known publishers of travel guides, like Fromm's.
It's obvious you posted the five star review yourself, as it simply repeats your blurb. I would pull that down, it will kill your sales.
Your book isn't too bad. I might would lower the price to 4.99 or 5.99. I might would change the cover a little. Maybe keep the girl but add a collage of some of those pictures of the sights of the city. Yes you do need to make the English better in the blurb and throughout the book. And yes do take down that 5 star review that repeats the blurb. Very unprofessional.
Yes, I'd probably drop the price to $5.99 or something in that range. I agree however, that you need a good review of your book by a native English speaker.
Then you need to promote your book in places where tourists are going to be looking for it. Perhaps bookmarks with the link to your book left at hotels in the area. Perhaps the same at travel agencies that cater to tourists to Thailand. There will be people that want your book, but you'll have to work hard to find them. If you can put out a series of these books over time cover many cities, you may do very well in the long run.
It is obvious to me also that the same person that wrote the description wrote the 5-star review. You can certainly deny it as it doesn't matter to me, but it will slow or even stop sales of the book. Readers do not appreciate this.
