Welcome back! There are tons of tanks available on Craigslist fully setup for $50 or so, if you don't mind getting used stuff, and if you are willing to watch and wait you can get top quality stuff for 1/10 the price. Since you're going low-light for plants, you won't have to go very fancy for lighting setup.
I don't know which crypt species you want, but there are a couple of members here who've had incredible crypt collections, but when the tank is up and running happily put out a call in the Swap and Shop section here listing your desired species, and you'll probably get both better stock and lower prices.
The best livestock in the area I've seen was at Tropic Isle, but it's a drive for you and usually a bit pricier. Msjinkzd is a sponsor here and has some pretty rad connections for livestock though, and could likely find almost anything given enough notice, or could pass you on to someone who could. Look up the "invertebrates by Msjinkzd" forum on the main page.
And most of all, peruse around and ask for any help you might need. The folks here are great.
