How to ACTUALLY Make a Good Sponsor?

so

I want to use the (kinda new maybe not) sponsor system, but I found nothing really helpful on how to get the best results

Budget

5k-6K Robux

- how long should I put the sponsor on for
- is my budget to low
- how much robux should i put in at the start
- what should I do with ad credits
- should I only sponsor to mobile users (my game is kinda targeted towards them)

And any general things I should know that will help

Thanks for your time, and i hope to see you in the replies
