For the lid:
1. You might be able to make one from 2x2s and hardware cloth or plexiglass. Frame it out like a glass door and fasten the materials together.
2. Check your local reptile and aquarium stores for these: http://www.amazon.com/s/ref=nb_sb_no...d%20tank%20lid
And here are the locks that work very well with those lids: http://www.amazon.com/Zilla-09732-Lo...inged+tank+lid
I used option 2 on my 55 gallon tanks and they worked well.

For the stand I'll leave that up to the uber DIY people and carpenters. You could try finding a cheap stand online or at a PETCO/Petsmart/aquarium store. Cheapest one i see on amazon is $190. http://www.amazon.com/s/ref=sr_pg_1?...qid=1398227690
