TikTok Ads and Content Ideas for my niche

I’m looking for someone who can guide me through TikTok Ads for my gaming-services business, so basically I'm looking for consultation. I mainly offer Apex Legends boosting, and also some Valorant and Marvel Rivals work, and I want to understand the right way to target players without wasting my budget. I’d like clear direction on which locations and age ranges make the most sense for these games, how to use my budget in the first week, and what kind of quick, simple content usually performs well. Nothing complicated, just practical advice I can apply right away. If we work well together I’m also open to continuing long term.
