Remodelling, looking for floor tile installers

I just purchased a condo in Zihuat and was quoted what I felt was a high price from a recommended architect to take out old tile and replace with travertine. From the start the price of material was 300% more than what I would pay from a local vendor I found on the internet. Then he reduced the tile price and hugely marked up the labour cost.

Can anyone recommend labourers and a tile expert who charge reasonable rates? I also want to strap and drywall the ceiling, put in pot lights and reposition the fans and add fresh paint throughout. I will be supplying the materials. Does anyone knows what going rates are? I have no problem paying the people doing the work more than going rate. I have a problem paying contractors who hugely inflate prices and then pay the labourers peanuts. I have a 2 bedroom, 2 bathroom 85m2 condo. Your advice and recommendation are much appreciated.
