[H] Tropico 5 4-pack [W] 3 TF2/CSGO keys each 4-pack + collateral

I have Tropico 5 4-pack and am looking to split opening the package for 3 TF2/CSGO keys each 4-pack + collateral.

I'll give preference to people with lots of reps and games on steam profile for opening this 4pack.
READ CAREFULLY BEFORE ADDING ME

Opening Tropico 5 4-pack for 3 TF2/CSGO keys each 4-pack + collateral Requirements:

1) 3 TF2/CSGO keys and collateral for each of the 4 pack (Please add me to discuss what collateral may be, I may also take other steam gift games you may have as collateral)

2) If you have excellent trading rep history with lots of reps AND a respectable Steam account I may do it without collateral, but I reserve the right to decide so.

3) You CANNOT already have Space Engineers in your Steam library

4) You MUST have bought something from steam store more than 30 days ago, or the extra copies will become non-tradable You are able to unpack the 4-pack, it will show like this http://i.imgur.com/odUbPpE.jpg (Picture found in the internet) If it shows like this http://i.imgur.com/nXTCSbt.jpg, the extra copies will not be trade-able How does it work?

1) I will give you Tropico 5 4-pack gift and you give me keys or steam gifts as collateral per each 4-pack

2) You then activate the 4-pack in your inventory, and soon after will receive the 3 extra gift copies of the games in your library

3) Finally you will trade me those 3 copies and I will give back your collateral.

Please post here before adding me on Steam so I will know who you are and why you are adding me for.
