I built this barb with a modest budget of about 450m and she can do mp 6 with ease. Elite packs take roughly 20 seconds to kill and staying alive is not a problem. Here is a breakdown of what things cost me:
You really should at least get a two piece IK set. The chest and the belt are a must, IMO for a budget build. Mine cost a whopping 90m but you can get one with less than 200 vit for 45m roughly. If you go with less than 100vit, you are looking at 5m or less. The ik belt is also a must since you get decent strength, Life steal, high all resist and some vit if you are lucky. My belt cost 4m. With no vit, it would have cost less than 1m. I also went with the IK helm which gives decent EHP for a modest price. Mine was 14m. You pay more for higher strength rolls and AR. You can get the same helm with no AR for less than 5m easily. I originally had a pair of ik boots with 120 strength and 90 vit and a total of 500 armor which cost about 2m. I upgraded to my ice climbers for 28m. You can go with IK gloves but you really need IAS to make WW shine and that is not cheap on ik gloves so I went with a cheap pair of rare gloves that cost about 5m.
I would spend no more than 2 or 3 million on shoulders with str,vit AR and armor if you can find some. I would focus more on vit since you will need it at first. You can craft some pretty nice shoulders easily and should be the first item you craft since they have the highest chance to roll decently. This is due to needing to really only hit 2 random rolls for decent shoulders....vit and ar.
You really need to get 24% movement speed for efficiency and Lacuni bracers and your boots are the most logical place. Innas pants can be good but their EHP is garbage and should only be used at high levels. You are looking at around 10m for a pair of pants with 230 vit 150 ish strength and 65 or more AR. For lacunis you can get AR + CC for cheap or strength plus CC. I think I paid 9m for mine. If you need AR, you can get a pair with 60 or so AR and 3% CC for less than 10m.
My amulet cost 8m. You will be crafting something much nicer so don't spend too much here. The SOJ Cost me a whopping 6m. Cold is better but the same ring will probably cost you 35m or more with a crappy skill. I originally had a rare ring with str, CC, IAS and CD which cost me about 14m but I upgraded to the unity at a cost of 55m.
Weapons are probably going to cost the most. My EF cost 150m. My first EF was similar except it had 940 dps and was 42m. You can save a lot here by not getting LS at all. 1.1k dps dps with a socket and strength should not cost any more than 15m. 6% LS from your ik belt and bloodthirst is enough to get you going. With lower dps I prefer 3 sources of lifesteal. My OH axe cost me 75m but you can get one with around 60 strength and 1k dps for 20m. With WW, your tornado damage is derived from the damage range of your MH weapon so getting a higher dps weapon even if it has minimal strength and no base crit damage is recommended.
Basically, I have 5200 armor, 560 AR, 50k life, 8.3% LS, 52% CC buffed with passives only, and I hit the 2.2 APS breakpoint with my OH and 2.5 APS with my MH. According to d3Rawr.com, I have 550k unbuffed EHP and 1.32m tDPS against elites with 22k life steal per second. As I already said, mp 6 is not difficult. I have played in mp 10 and I can surive but it takes so long to kill elites that it is painful. There is nothing efficient about taking 2 minutes on an elite pack.
You can go with a cheaper IK chest, EF, Ring, boots and MH weapon and save yourself over 250m and probably only lose 10k health and maybe 25 or 30k dps. 110 or 115k dps is still pretty decent for mp 5.
I think 300m is a good round number to aim for or about $25 like Codey said. I would stick with a WW build since it is fast and dishes out a ton of damage. HOTA is great for ubers but farming with HOTA takes too long, IMO. BTW, I have another account with about 58k elite kills on it. This is one of my multibox farmers.
