Hello
I don't see that there is any need to mention you only have 2 bouncers and let readers make the wrong assumptions if they wish.
I write blog articles for both a vintage photo booth company and what we call 'bouncy castle' company here in the UK so I understand the products. While many companies promote bouncers for kids, they are becoming very popular at weddings, which goes really well with the photo booth.
A landing page is just that, it is where people 'land' when they come to a website so they don't want to be inundated with information. Instead you need only around 300 words reassuring anyone who has come to your website that they have come to the right place. Research will show you that the imagery is more important than the words, so you need to make it crystal clear whet you are offering - the wording is just a back-up.
Finally, while it would be wonderful if everyone who landed on your site booked your products straight off the bat. However experience tells me that it is safer to aim to get people to call you and do the selling of your services one-on-one. This while the content will strongly hint at hiring your equipment, the call to action will be to contact you, not hire your products.
I hope that makes some sense and that it is clear from my feedback, completion rate and 98% pass for US English that I work to very high standards. The copy supplied will be work in progress and subject to one round of revisions before final approval is sought.
