There used to be a community at pulsareffect.com
I'm not sure what happened to it but they used to host 5 GMOD servers, each with a different game mode.
I was often on 3 of the 5, a GMOD racing server, Role play lite and Role play serious, (Not as nerdy as it sounds
).
The servers were very popular and I'm not sure why they died, maybe a GMOD fanatic among us has more info.
Anyway, key note is that they would charge $22 (about £13 or £14) for VIP access on all 5 servers.
VIP access would grant you additional features and bonuses in the 5 servers.
For example, in the racing server it would allow you to buy guns and ion cannons which normal players would not be able to use, also allow you to use custom skins for the racing car (The buggy model was used) rather than the standard rusty skin, give you an extra 25% payment* and a reserved slot.
(The actual game mode is that you start off with a standard car and as you gain money you upgrade it with Nos, brake pads, ramming spikes, armor, aforementioned guns, car radio, maybe a horn, power steering etc.)
*The payment refers to the amount of money that you win per race.
The role play server also granted you the 25% increase in payment, aswell as access to jobs that normal players couldn't get such as a place on the swat team and oher bonuses.
So, basic suggestion is to do something similar.
