I have a grass tennis court so spend a lot of time on my lawn. Evergreen Complete is the only decent Evergreen product they do. I use it for weeds and it will work if you use the Evergreen spreader (about �29) to get the correct amount on the lawn. It may take 2 aplications over 5-6 weeks. I then use Pentagon Prestige High NK (This you Can Not get at BNQ, Homebase, etc...) This makes the lawn a nice healthy green. I get it from a place called Collier Turf Care.

(They deliver to some of the best lawns in the UK) You could phone up and ask for a product and price guide, it has every product for your lawn you can think of. You will end up with a lawn like centre court wimbledon. Hope this helps mate, sorry it was so long.
