I need help, badly!

I need help, badly!

Good evening, Ladies. I need help so badly! We are getting ready to sell our house and, we are in dire need of landscaping advice. My husband and I had a deal, the inside of the house is my domain, and the outside is his. Well, I wish he could have stuck to his word! He rarely mows and the flower bed? Ugh...Just look at it. Photobucket I'm now having to take over his chores, because no one is going to buy a house with a yard like ours. I'm having a company come out to mow, weed eat, edge and cut all the trees back. I hate having to throw money at that problem...but I have a 4 month old and I can barely find time for a shower these days. I'm going to dominate this flower bed myself, I just need advice (REALLY dumbed-down advice). It has weeds and grass growing in the bed. Where do I even begin? I don't mind keeping the monkey grass, but how to get rid of everything else? Shovel it all out, lay plastic?, lay down new soil, and some kind of ground cover (mulch, pine needles?). Any help would be SOOO nice! :/
