Site improvements on Wordpress

It is necessary to periodically make changes on my Wordpress site.
Since the site was created and will continue to evolve, it is not the last job and I dont want every time to look for a contractor on every edit, and in the subsequent design and SEO.

Therefore counting on long-term cooperation, and given the fact that I work with businesses that including need sites and revisions, long-term and as valuable to me in twins.

What specifically interested now post the link:

Please send in the response message:
1. The cost for each of the works
2. Your portfolio
3. The cost of an hour of your work

Important point! With a suitable contractor want to talk voice, to have an idea about you.
No verbal dialogue to cooperate we cant.
Not looking for the cheapest price, but will not agree to high prices.
My business is to help other businesses, ie, essentially your quality of work is my quality, so will choose carefully.
And of course we will develop and agree on TOR, so you do not have mutual claims.

Good luck and good mood to work.
