Ohh, a real tuff one!
Normally I use different tents depending on the hike profile. But I understand that investing in a tent for every season is not for every one.
It sound like you need a tipi style of tent. However, listed bellow is a few tents that you can take a look at. Two 4p tents, and one 1p tent. But I must warn you that I had no chance matching the price you specified.
