I agree with your expression, but unfortunately I can't find another service. But I would be very glad if you could tell me where to find another option? I was told to try to find one in social networks.

How much would it cost to subscribe to a site with music without copyrights? I found one service that asks from $30 a month, this is for the cheapest plan. The most expensive one is more than $70 a month.

Of course, such a check is necessary. 18% of children in the U.S.A. have access to the Internet and websites for adults. But you don't need to add a button to the site. It's better to use pop-ups. I have recently found a new service that allows you to create pop-ups quickly and integrate them into your site. There's also an article there about age verification pop-ups https://claspo.io/blog/age-verification-pop-up-why-do-you-need-it-and-how-to-add-one-to-your-website/ . The interface is simple, and it's not hard to operate.

I can give you the contacts of one company which you can contact and order android application development https://owlab.group/services/android-app-development there.

We are launching a small web application in the UK. The web application needs a normal server. To handle the load. We are in desperate need of a good vps server. Should I buy it in another European country or should I buy a UK server?

A virtual server is enough for that many users. But when you have more users on the site. Then you need a lot more. You need to buy a physical server, it will cost many times more.
