Normaly no funding is enough for a dexless sin. But you seem to be on a good track, there are TONS of quests that give you 60% glove att and a lvl 25 one that will give you a scroll. that should fund you, and then get some tobis and +7 your maple claw, that will do it untill you go for godly equips.
Also, a dexless sin is really ment to be a side char, for someone with high lvls that wants to have some fun and has tons of money, really id call it quits. If you wanted to start on a new server you shoulda made a simple normal side stat build char.
Also capping your dex is all about funding the poorer you are the higher your cap.
