judging by what forum this is is I assume he isn't going to need lights. But I'm glad you mentioned PH and lime.
If you have a very clay-ey soil your ph is gonna be pretty high probably like 8 or 9 and you want it just below 6. you can get a really inexpensive (5$) ph meter at any store that carries garden supplies, but if you dont get one it really isnt a big deal. get some lime and spread a couple handfuls across your plot and work it into the soil. Check it with the ph meter to get it around 5.5-5.8 and that will solve that problem.
As far as your budget goes how many are you planning to grow? seeds are expensive to order but IMO the best way to go if you can't get clones, although on occasion bagseed turns out okay.
When buying soil additives the very most you should need to spend would be around 150 bucks and thats if you buy a few bags of real good expensive soil. If not, the nutrients necessary should keep you under the 200$ budget.
