Anyone here good with coming up with Earth-like realistic climate/biomes?

[justokre]

I'd like someone to finish the technical aspect of my map for me.
Correspondence is good.
More work available if the job and price are right.

Here's the work-in-progress:


What I want:
Use my photoshop file
Add a new big continent or two to the east
Normalize the continent borders of entire map so they look like they belong together
Add relief-style mountain ranges and rivers in realistic places, taking tectonic plates into consideration
Come up with biomes for entire planet, based on Earth models. The more information and map layers you can give me, the better.
I'd like layers with believably realistic rivers, lakes, mountains, and biomes.

Style
Example of relief mountains I like: CK2.
Example of biomes I am looking for. First (album). Second.
Coastlines I like, not the stamped mountains: Here.

Quality/Size
I'm thinking roughly 5k x 2.5k pixels.
For web usage for now.
