Is Cheap, Western-style housing possible to find in Lagos, Nigeria??

Hey everybody, I'll be moving to Lagos, Nigeria next week for a 6-month assignment. Though I was there a couple weeks ago on a preliminary trip, I had trouble finding housing in the range of what the small startup business I work for can afford. More specifically, my price range is 400-450k naira TOTAL (about $2500-$3000), again, for six months. I've been looking at websites and in person with a few property agents in search of fairly nice (Western standards-ish) and safe apartments or guesthouses to this end in Lekki, VI, Ikoyi, Island, VGC, Yaba, Surulere, and even other areas. Thus far, I've discovered only one or two places that are both safe/nice and meet my budget. Is this a lost cause in Lagos? Does anybody have some advice? Thanks in advance for your time, Kevin
