letter about thanking a friend for sending photos of holiday

Dear alireza,
Hoping you are in the pink,I am writing to you concerning the photos of that enjoyable
holiday we have had recently.
First of all,I am extremely grateful for the favor you have done me sending the photos of
holiday which evoke memories of that calming and rewarding day to me.
However,having not been in touch for a long term,I have to say that getting involved with
Business affairs prevented me to write you earlier.
As a matter of fact, I have been having hectic days full of activities ,lots of meetings with
Businessmen ,spending time to estimate the shares' value , predicting stockmarket's future outcome
and so on all lead me not to be able to meet your expectations to write you sooner.
All in all, hoping you entitle me for the belated letter, I propose you to come to my my homeland
and stay with me assuring you that you are going to have a pleasure time here.
I will give you my word that you will experience a relaxing time here visiting one of our scenic
landscapes in our ancestral village.
Yours faithfully,
Mohammad

1. readers can tell u r so busy...but "have been having hectic" is busy with grammar error and redundancy. (bear with my rude. pls...)

2. i guess there should be a sentense break here. and it is better to re-organize this sentence.
