Help from discount kitchen sinks

It would be nice to re-do our kitchen. Maybe just to make it a little bit bigger so there's more room. When hubby cooks he always take the entire space of the kitchen and leaving me waiting for him when he gets done at least using the sinks. We have the double sinks but it is not enough for both us working at the same time. It really annoys that I have to wait. We did talk about it, however weren’t not sure because of our thinking of moving. But I told him maybe replace a bigger sink; there's many discount kitchen sinks that will help our budget. We’ll take this into consideration for sure just to help the agony of working together in the kitchen.
