I will answer by telling you what I am doing. There are two different ways:
1.
Hire someone to translate your current content - main pages and the reviews. The process with the reviews about the different casinos, poker or bookmakers is hard to do, because most of them offers different bonuses for almost each country. This would be the hard part - the chapters with the bonuses should be appropriate for the specific country!
2.
Hire very good content writers and send them some content structure (no translation of your current content!). Let's say if you want a review of Bet365, then just tell them that you need a review about Bet365 but don't forget to mention the structure.
Example:
1. Introduction (or About Bet365)
2. How to register at Bet365
3. Betting markets
4. 100% bonus for new customers
5. In-Play feature
5.1 Live stream option
6. Cash out
7. Deposits and withdrawals
8. Mobile version and applications
9. Final verdict and rating
This is my example of how you can do it. The content with your pages should be the same. Just think about your content and how you will want to be structured. The more you are detailed to the content writers , the more you will be satistified.
*I personally hired people or companies from Freelancers but be careful - Hire only writers which has SUPER rating and many projects behind their portfolio
