you might consider instead of home depot lights looking for olde lowel lights ( now they are called "L" lights) you can usually find them on feebay for way under 100$ for a 6-light kit. they take floods instead and places like or have daylight floods ... i have a bunch of them bought cheep ... i don't use them with soft boxes - i think lowel light also makes soft boxes - for their hotlights ..

you might consider doing "bounce" with foam core - it would be cheeper than a softbox THAT is for sure

good luck!
