The time to build the customer order may vary depending on the needs you have, usually the average number of customers who have been satisfied, have been served on average for 3 days. if the constructions are too large this may take longer

No, you cannot make the construction on a server other than the constructor, he map will be made on the local server of the constructor, since this server will be fully configured and optimized for constructions, it will also have its own plugins, for this reason it is impossible to build the map on a foreign server.

The answer is no, you can not download these maps for free because they are for customers who wish to buy, also you can not trust the map to be paid later.

Depending on the server, I can belong to the staff, with the simple condition that the constructions that are needed will be paid, in the same way over time a discount will be obtained by preferential customers

The answer is yes, it can make your order run faster.
There are usually many customers requesting orders, which leads to a queue of customers, the solution is to be a priority customer, this means paying an additional to your order, and also paying it in advance, in order to ensure a fixed turn after finishing the current order, no matter how many people are waiting, simply the builder will continue with your order.
