Open up services here on Sythe but given the number of vouches, that'll take a quite some time before things get rolling. Uhm, you can try your luck with staking with small stakes. There isn't really many options other than just buying RSGP or doing the above.
Start up a service here or sythe and either ask for rsgp payment or some other kind, but since you don't seem to have vouches not a lot of people will come to you for services so offer some free ones first.
