we would like to make a banner using this logo so we would like the dimensions to be  compatible with a 2X8 or at least a 2X6 ft banner. also we would like the resolution to be high enough to look good if enlarged to such size.  the mushrooms we produce are Oyster, Reishi, Lions Mane , shiitake, and none of the usual ones you see in the store so may want to be careful about which mushroom pictures you use. white background is great but real pictures of produce and herbs will be fine also. we will have basil, tarragon, etc. 
Our purpose is to feed people great food that comes from good sources. if this idea can be reflected in the logo it would be great.

Shere is great, i still need some modifications from him.
