What Dyu Know Of These Biz Ideas

1-setting up a proper distribution network for all the nollywood movie dvds and artise cds e.t.c like hmv or virgin in the united kingdom,at the moment its a major problem with the practitioners and i believe it will go a long way in adressing the problems of piracy and also theres a lot of money to be made there as well,please if you have any idea about doing this please contribute.

2-a lifestyle/romance magazine either bi weekly/monthly,what does it entail ,is there a market for it in nigeria and how much will it take to run e.t.c
