I'm helping my wife to run an e-commerce platform. Compared to the traditional brick-and-mortar retail shop where potential customers can physically check the sale item, online marketplace relies heavily on the posted photos to do the talking.

We would like to have all our products to be displayed on white background. We also plan to shoot video for product reviews. Due to our business model, both of us think that we need to slowly rebuild our AV equipment (yeah, I sort of "quit" photography for quite some time...). There might be certain occasion when we need to bring our soon-to-be-acquired equipment outside. Mobility is a must.

With limited budget and in mind (most of the $$$ went towards setting up the biz), what would you propose for our setup? Doesn't matter used or new as long as cheap and reliable.

DSLR - Good for photo & video (HD). I used D7000 last time. Still can consider other brands and models.
Lenses - Maybe one prime, one zoom
Lighting - Continuous lighting perhaps? LED vs CFL? 3 lights setup with softboxes?
Mic/voice recorder - H4n?
Any other things that I miss...

Maybe you guys can start with "If I were you, ..."

Thank you in advance!
