Hi MadKidGames Team,

I saw your post on the HTML5GameDevs forum looking for a custom Ad SDK developer. I am a Low-level Web & Systems Developer, and I can build this lightweight JavaScript SDK for you.

Since I have experience building virtual machines (VMs) and custom systems from scratch in JavaScript, building a highly scalable, lightweight Ad SDK that hooks into Google Ad Manager (GAM) for Rewarded, Interstitial, and Banner ads is right up my alley.

What I can deliver:

1. A pure, lightweight JS SDK (Single file deployment, ultra-fast loading for HTML5/Unity WebGL setups).
2. Smooth integration with GAM ad tags and listeners.
3. Clean documentation so your game developers can integrate it with a single line of code.

Pricing: I can execute this full SDK development for a fixed price of $1,500.
Timeline: I can deliver the functional initial prototype within 24 to 48 hours due to my rapid development speed.
Payment: Ready to work via Direct Agreement (PayPal).

If you are ready to get started immediately, let me know, and we can discuss the technical API endpoints right now.

Best regards,
Ges Studio
