Go with a dwarf barbarian and start with 18 str and at least 16 con. you wont need any cha so the 6 will be fine.
make sure at every level chance put the extra point into str. Use great axes and leave power attack on. By higher levels you will not be missing at all. At lower levels use the highest +weapon you can so you don't miss then. Rage Rage Rage
This way you will know what real DPS is like and not waste your time in the future with a crappy dex build because you were able to do real DPS and have a good point of reference damagewise.
When people look for melee type they will not be disappointed by the damage you do. Being a dwarf you will end up with a lot of HP. If you put rogue levels your evasion will be bad as your reflex save will be bad, plus you will lose a BAB. if you add to dex with this 28 pointer your str and con will suffer, which are the most essential for a barb. go pure barb or if you must sneak in 2 levels of fighter for feats. yo0u will have enough HP to make up for the lack of evasion.
Stay true to this and dont try and do too much and this toon will be a very viable build to get your 1750
