Best WHMCS Website Integration Services?

Hi,

Im looking for a company who can integrate my WHMCS with my Wordpress design, in order that my WHMCS design looks similar to my website.

Until now i have found 4 companies that do that kind of service and i leave you a pool in order that anyone who has experience can share in order to help me making the right decision on wich company i will hire to match my WHMCS design with my Website.

Companies that i have found until now:

a) WHMCS Official Team - www.whmcs.com/services/integration/
b) www.whmcsthemes.com
c) www.whmcsintegration.ca
d) www.zomex.com

Please share your experiences and please vote on what of this 3 companies do you think is the best.

For me on this project money is no problem. Im just want to find a quality company that can make a very good integration of my Wordpress website with my WHMCS.

Also if you know any other quality company that can make this kind of service and its not listed above, please fell free to share

Thanks
