Forex / Guide () org is not bad as name, but a little bad for extension. I think it can go for mid-high $xx.
Dating / Advices () com is nice too, if good developed it has good potential. And if you find an end user (it wouldn't be so difficult), even mid-high $xxx is a realistic figure. In the reseller market (esp. with developer) it hardly go over low $xxx, but you can try.
