logo design for agricultural products

Clients brief: As discussed i really want to establish an effective and simple business logo. I want it to be simple and reflective of my business. It must be easily recognisable. I want the logo for everything such as invoices, packing tape, bags etc. If we can keep the number of colours down to maybe a green or a black then we can cut the cost of printing. I like the idea of having two symbols to represnet my Agri supply business, one being grass the other being livestock, so i had a look at the web for pictures by putting what i wanted into Google and trwaling through the pictures that came up. So i have attached a few of those pictures along with a layout on a word file with the old logo at the top. I really like the idea of blending the cow or whatever cattle symbol works with whatever grass symbol works, and adding "CDS Agri" into the mix some way. I think i would be good to get the logo work done first so as we can add it to future work such as delivery dockets, brochures etc. I'm open to any different suggestions you may have.
